Music Studio: Key Finder
A new practice game in Music Studio. Key Finder shows a four-chord progression and asks which major key it belongs to. You work it out with four quick rules: two major chords a whole step apart are IV and V; two minor chords a whole step apart are ii and iii; a minor chord with a major chord a half step higher is iii and IV; and a major chord with a minor chord a fifth higher is V and ii. Pick from the 12 keys. Then the answer is revealed with a Roman numeral under every chord, and each rule that gives the key away is named, with its chord pair ringed. Stuck? A hint rings the telltale pair first. You can also play the progression to hear it. Twelve progressions cover all twelve keys, dealt in a fresh shuffle each session.
-
› four chords, twelve keys: name the major key
-
› the four key-finding rules sit on a cheat sheet right on the page
-
› after you answer, every chord gets its Roman numeral and every matching rule is called out
-
› a hint rings the telltale chord pair, and you can play the progression to hear it

Every app banner, remastered — and the night city comes alive
The animated pixel-art headers on Radio, Sports Bar, Arcade, Music Studio, Study, Lab and Food Court have all been redrawn by hand: same rooms, same characters, more craft. Light is painted into each scene instead of washed over it, surfaces keep clean bands of colour instead of a screen-door dither, faces got friendlier, and everyone moves in held poses rather than a constant wobble. Several scenes are now playful: tap the guitar in Music Studio and the musician walks over and plays it (tap the piano to send him back); tap the pup in Study or Music Studio and it hops up surprised; the Food Court stalls are staffed and bustling, with an open grill that flares. The city theme's homepage backdrop is rebuilt as a whole night city: a real crescent moon, clouds drifting behind the skyline, towers with setbacks and water tanks, an elevated train crossing between the buildings, and a street full of life — passers-by, a busker, a food cart, a subway entrance, neon club signs and traffic that actually drives, queueing at a red light and overtaking the bus.

Radio: save a track, play it again, send it to a friend
Radio's promise — you'll hear something no one else has — came with an unadvertised cost: you'd never hear it again. Every track was composed from a throwaway random number, so the one you loved vanished the moment it rolled over. Now every track is composed from a fixed seed, which makes each one a stable address: the same station and seed regenerate the same music, note for note, on any browser. That unlocks three things on the brass spec plate. ♥ saves the current track to a list under the radio (kept in your browser); ▶ on any saved row plays it again; the link button copies a permalink — open it and the needle is already parked on that station with the track's name in the window, one power press from hearing exactly what your friend heard. Under the hood the live engine and the composer's test harness now share one seeded generator instead of two RNG paths.
-
› every track is a stable (station, seed) pair — replaying one regenerates the identical music
-
› ♥ on the spec plate saves the current track; a saved-tracks list sits under the radio with play-again, copy-link, and remove
-
› the link button copies a shareable permalink (?station=jazz&t=…) that pre-tunes the dial and shows the track's title before you press power
-
› track titles are derived from the seed too, so a saved track keeps its name across sessions
-
› saved tracks live in your browser (localStorage), alongside the dial position and volume — no account needed

New York City, textured from the real map
The Geography explorer's 3D New York used to sit on a flat tan ground with a made-up street grid, and every building was a plain coloured box. The ground is now painted from OpenStreetMap: the real arterial network — every expressway, parkway, avenue and boulevard, Broadway cutting its true diagonal across the grid — plus mainline rail, the actual runways at JFK and LaGuardia in their true orientations, and hundreds of real parks, cemeteries, golf courses, beaches and industrial waterfronts, all clipped to the coastline. Buildings wear facades tuned to their height: brick brownstones, pre-war masonry, glass curtain walls and supertall spires, each with lit windows and a proper roof. The harbour gets real chop from a normal map, and the land a fine grain instead of flat plastic. It is all still drawn on your device from vector data, so it stays sharp at any zoom and nothing is fetched while you explore.

Pool Shark's balls actually roll now
Pool Shark has always simulated a ball's spin — sliding and rolling friction, follow and draw, english off the cushions, throw between balls — but you couldn't see any of it, because the balls were drawn as flat discs with the number pinned facing you. They slid across the cloth like air hockey pucks. Every ball now carries its own orientation through the physics, and the number, the stripe and the white polar circles are projected onto the sphere from it. A ball turns exactly once per circumference it travels, rolls its number over the horizon and back into view, and keeps whatever it was left with when it stops. Backspin visibly drags the surface backwards while the cue ball is still going forwards, and the cue ball is now a dotted training ball so its english is readable too.
-
› balls rotate as they roll — one turn per circumference, taken straight from the spin the physics already tracked
-
› numbers, stripes and polar circles are projected onto the sphere, so they curve away and vanish over the ball's edge
-
› follow, draw and english all read off the surface: backspin drags the print backwards under a ball that's still moving forwards
-
› the cue ball is a dotted "measle" training ball, the standard way to see spin on an otherwise blank ball

Arcade remembers your bests — and syncs them to your account
Until now the Arcade forgot you the moment you left: Cascade's high score lived only in one browser, and Pong, Sudoku and Jigsaw kept nothing at all — switch from laptop to phone or clear your browser and every result was gone. Now each game records its result when it ends: Pong keeps your win–loss record against the AI, Cascade your best score, Sudoku and Jigsaw your fastest solve (with the difficulty or piece count that set it) — plus how many you've played. Signed in, those bests live on your account and follow you to every device; the first time you sign in on a browser that already has bests, they're adopted rather than lost. Not signed in, they're still saved in that browser. The Arcade hub gains a compact "your bests" strip so a return visit shows your history at a glance, and each game's end screen shows where this run stands against your record.
-
› Pong: lifetime win–loss record vs the AI, shown on the game-over screen

New Arcade game: Pool Shark
The Arcade's sixth game is a billiards table built for learning 8-ball, not just playing it. The physics is the real thing — balls slide before they roll, follow and draw come from where you strike the cue ball, side english squirts the cue ball off line and throws the object ball, and cushions bend a spinning ball's rebound — so what works here works on a real table. Because the engine is deterministic, the coach assist runs your exact shot ahead of time and draws the true predicted paths: the ghost ball, the cut angle in degrees, where the object ball goes and where the cue ball ends up, including any pocket or scratch. Dial the assist down to ghost-ball-only or off as your aim improves. Practice mode counts innings while you run the table solo; two-player mode is pass-and-play on one screen. Works with a mouse or a thumb — drag to aim, slider for power, drag the small cue ball to add spin — and the table turns portrait on a phone.
-
› realistic physics: sliding/rolling friction, follow, draw, english, squirt, throw, and cushion spin
-
› coach assist simulates your exact shot: ghost ball, cut angle, object and cue ball paths, pocket or scratch warning
-
› three assist levels — coach, ghost ball only, or off — so training wheels come off gradually

NFL pre-season games in Sports Bar
August meant an empty NFL section — the schedule and scores pages only ever showed regular-season games, and the regular season doesn't start until September. ESPN's scoreboard already includes pre-season matchups by default, so the Schedule, Scores, and hub ticker/All-tab feeds now surface them too, live-updating through the same poller path as any other game, with a clear amber "Pre" chip everywhere they appear (game cards, the ticker, and the game-detail header) so they're never mistaken for a regular-season result. Standings stay untouched — they're sourced from ESPN's separate standings endpoint, never from scoreboard events — and once the regular season kicks off the chip simply stops appearing; no separate on/off switch needed.

New Lab demo: ETS Tables
The Elixir & OTP section covered processes, GenServers, Tasks, and messaging — but not ETS, the in-memory table layer real Phoenix code leans on constantly (this very site uses ETS caches for sports scores). The new ETS Tables demo gives you a real per-session table: insert and delete rows live, look one up, run a match/select query, and — the core lesson — apply the exact same inserts to a fresh :set, a :bag, and an :ordered_set table side by side to see how each one actually handles a repeated key. A 6-step guided tour walks through :ets.new, insert, lookup, delete, select, and the three-way type contrast.

Theory: Roman numerals — the chord/key rung above scales and triads
Theory could already drill scales, triads, and seventh chords in isolation — but nothing taught the mapping between a chord and its function inside a key, the conceptual rung that makes yesterday's progression ear-training actually meaningful: that Dm *is* ii in C major. A new Roman Numerals deck flips a chord-in-key to its Roman numeral and back ("Dm in C major" ↔ "ii"), covering every diatonic triad and secondary dominant across 9 major and 9 minor keys — the same Secondary Dominants reference chart the app already ships, now a real flashcard deck instead of a look-up page. FSRS-scheduled like every other Theory deck, and it shows up automatically in "Study all due."

The hub ticker finally tells scheduled games apart
The Sports Bar hub's scrolling ticker shows the today±2 window at a glance, but a scheduled game only ever carried ESPN's raw status text — often just the word "Scheduled", so three straight days of the same matchup all looked identical with no way to tell which was tonight's game. Scheduled games now get a compact start time in your own timezone ("7:10 PM"), with a day chip ("Tomorrow", "Tue") in front whenever the game isn't today. Latest results also stopped showing a misleading "0 – 0" for postponed games — the score is suppressed instead of implying the game was actually played and tied.
-
› scheduled games in the ticker show a compact start time in your timezone, e.g. "7:10 PM"

Ear Training: hear the progression, not just the chord
Ear Training could already drill an interval or a chord quality in isolation — but functional hearing, the skill that actually matters, is recognizing how chords move together. A new Progressions module plays a short diatonic progression (I–V–vi–IV, ii–V–I, and four more) through the same audio you already know, and asks you to name it by Roman numeral rather than by key — the same progression sounds the same whether it's played in C or G, which is the whole point. FSRS-scheduled like every other card type, and it shows up automatically in "Study all due."

See what's coming: an FSRS forecast on the Studio hub
The Progress section already showed where you'd been — accuracy trends, leech cards, a daily activity heatmap. It's now got a forward-looking view too, straight from the FSRS scheduler that already runs every review: a 7-day bar chart of reviews coming due (with a 30-day total alongside it), a current recall estimate per section ("~92% recall"), and a mastery snapshot showing how many cards are still being learned versus mastered. Theory — which has no per-review history to chart accuracy or response time from — gets its own version of the recall + mastery picture for the first time, since that only needs FSRS's current state, not a review log. Nothing new to track: every number here already existed inside the scheduler, just not surfaced until now.

Kitchen's ingredient picker is now searchable
Kitchen's picker (from yesterday's Recipe Finder + Meal Planner merge) inherited a findability gap: about 50 chips spread across five category blocks with no way to jump straight to one ingredient, and on a phone the search/plan buttons sat below a wall of chips. A type-to-filter search box now sits above the picker — type a few letters and every category narrows to just the matching chips, herbs & spices included (its section opens automatically while a search has a match inside it). A compact "N selected" count sits right next to the search box, so you can see your pantry size without scrolling. None of this touches your actual pantry selection — clearing the search always brings every chip straight back.

Notestar journal: rotating reflection prompts
The Journal's "Gentle nudges" mode used to greet an empty entry with the same static placeholder every day. It now shows a rotating reflection prompt instead — a short question like "What drained you today?" or "What's one thing you'd repeat tomorrow?" — pulled from a bank that varies by day of the week, so Monday's prompts aren't Sunday's. Not feeling it? "Try another" cycles to the next prompt in that day's bank, no server round-trip. "Use this prompt" drops it into the entry as a quoted heading to write under; otherwise it's just guidance — start typing and it disappears, and nothing about it is ever saved unless you write something yourself. A non-empty entry never shows it, and it never appears at all in Guided template or Daily review mode, which already prefill the entry a different way.

Recipe Finder and Meal Planner merged into Kitchen
Two sub-apps used to run the same pantry idea in parallel: Recipe Finder matched ingredients you picked, and Meal Planner built a week from a dataset that had never heard of your pantry. Kitchen (`/kitchen`) is the merge — one ingredient picker feeding both find-something-now and plan-my-week, switchable without losing your selection. Planning is now pantry-aware: generation prefers meals your pantry already covers, a meal it can't fully cover still gets scheduled (a week has to fill) but is labeled with exactly what it still needs, and the shopping list only lists what's actually missing. Herbs & spices default to fully selected and start collapsed — most kitchens have a spice rack, and assuming otherwise just added noise — expand the section any time to deselect what you don't stock. `/recipes` and `/planner` keep working via a redirect.

New Lab demo: Tasks & Async
The Elixir & OTP section had demos for spawning raw processes and running a GenServer, but nothing for the concurrency primitive most Elixir code actually reaches for: Task. The new Tasks & Async demo lets you launch a batch of real, bounded Task.async processes and watch them run — then contrasts the two ways to collect them. Task.await_many launches everything at once and hands results back in the order you submitted them, no matter which one finished first. Task.async_stream caps how many run at once and streams results back live as each one completes. A guided tour walks through both, plus a one-line takeaway for each.

Theory, Reading, and Ear Training each track their own due cards, which meant three separate sessions to clear a day's review. The hub now offers "Study all due" — one interleaved queue that draws from all three sections at once, so a Theory card is followed by a Reading card is followed by an Ear Training card instead of grinding through one section at a time. Each card still renders with its section's own interaction (flip-and-rate flashcards, or multiple choice with audio) and every review is still recorded through that section's own spaced-repetition schedule — this just changes the order you see them in.

Refreshing mid-puzzle, or closing the tab and coming back later, used to hand you a brand-new stranger identity — new name, new color, and your scoreboard credit gone.

Sports Bar opens on every league at once
Sports Bar was five sealed rooms: NFL, MLB, NBA, MLS and the World Cup, one at a time, with no way to ask "what's on right now?" without clicking through all of them. There is now an "All" tab, first in the league nav and the one a fresh visit lands on. All Scores and All Schedule show every league's games at once, grouped under a league header so each slate stays readable. All Standings stacks each league's own table — the conference-and-division shapes and the points-based ones are genuinely different, so nothing is forced into one grid; collapse the leagues you don't follow. Picking a league still works exactly as it did, still sticks for your next visit, and a link straight to, say, MLB standings still opens MLB standings. None of this adds any new data fetching: All reads the same live caches the league pages already read. Your Teams moved off the hub into More, where it isn't competing with the scores.

Restaurant Roulette's craving picker got a lot smaller
The picker used to be a wall of ~20 buttons — cuisines and qualities both fully spelled out whether you wanted them or not — pushing the zip code and Find food button off the bottom of the screen on a phone. It's now a search box per category: type a few letters of what you're craving, pick it from the browser's own suggestions, and it shows up as a small removable chip. No new library shipped for this — it's a plain text input and the browser's built-in autocomplete list, so it's keyboard- and screen-reader-friendly by default. Selecting and matching work exactly as before; only how you get there changed.
-
› cuisines and qualities are now two searchable boxes instead of ~20 always-visible chips
-
› the phone layout finally shows the zip code and Find food button without scrolling past the picker
-
› selected cravings still show as chips you can remove with one tap
-
› built entirely from native HTML — no autocomplete library was added

Every Restaurant Roulette listing now shows its work
A review of the roulette's restaurant list turned up a problem in its oldest entries: the original listings for New York, Los Angeles, Chicago, Austin, San Francisco and the first Portland neighborhoods couldn't be matched to real businesses. A few sat at addresses that are office buildings rather than restaurants, and a few carried the wrong zip code for their own street. All 36 are gone. In their place are 42 venues checked one at a time against the restaurant's own website — the address it prints and the dishes on its menu — and every listing now records the page that check came from and the date it happened. A couple of neighborhoods came out smaller than they were, and one has no pizzeria at the moment. That's deliberate: a shorter list you can actually turn up to beats a longer one you can't.
-
› 36 listings that couldn't be traced to a real business were removed
-
› 42 replacements, each checked against the venue's own site for both address and menu
-
› every listing carries the source it was verified against, and a test now rejects one that doesn't
-
› coordinates are geocoded from the street address and cross-checked against two mapping services
-
› no more same-block duplicates in St. Johns

Restaurant Roulette actually spins now
It's called Roulette, but hitting "Find food" just swapped one card for another — correct and completely flat. The pick now arrives with a short slot-machine reveal: the cuisine line riffles through the craving categories while the restaurant name and the dish blur through a run of characters, and the three lines snap into place one after another. The whole thing is over in under a second, and it is pure decoration — the result, the distance, and the Re-roll button are all there and clickable the instant the server answers, so nothing about finding food got slower. Re-roll mid-spin and the reveal simply restarts on the new pick. If your device asks for reduced motion, you get the finished card with no spin at all.
-
› the cuisine, restaurant and dish lines settle in sequence, done in under a second
-
› the reveal decorates the result — it never delays it, and Re-roll works during the spin
-
› prefers-reduced-motion gets the complete, static card instead

Roulette sends your zip code to the food that's actually closest
When the metro expansion added Beaverton, Tigard and Gresham pools, a handful of west- and east-side zip codes were left pointing at the Portland pool they had always used. Searching 97225 "within 5 miles" reported nothing nearby while a Beaverton restaurant sat a mile and a half away — the pool was picked before the distance filter ever ran. Nine zip codes now resolve to the nearest pool we cover, and a test measures every covered zip against every pool, so the next batch of restaurants can't quietly strand one. The "nothing that close" message no longer claims we have restaurants in a zip code that has none of its own, either.
-
› 97219, 97221, 97225, 97229, 97230, 97231, 97233, 97236 and 97239 now reach their nearest pool
-
› 97225 within 5 miles goes from "nothing nearby" to a restaurant 1.4 miles away
-
› routing is distance-checked in CI, so the next batch of restaurants can't leave a zip code pointed miles past a nearer pool

Restaurant Roulette now covers the whole Portland metro
Roulette used to stop at the Portland city line, and St. Johns — the one zip the whole feature was built around — had a pool small enough that a couple of re-rolls saw everything there was to see. That zip gained eight restaurants, spanning pizza, Mexican, Thai, sushi, Indian, Hawaiian barbecue, breakfast and pub food. The suburbs are in too: Beaverton, Lake Oswego, Milwaukie and Oak Grove, Tigard, and Gresham all return real picks now instead of "we don't have that zip code yet." Every restaurant added is an actual business at an actual address — verified one at a time, with the ones that had quietly closed left out.
-
› the 97203 / St. Johns pool gained 8 verified restaurants
-
› Beaverton, Lake Oswego, Milwaukie/Oak Grove, Tigard and Gresham zips now return results

Restaurant Roulette asks how far you'll go
Roulette matched on cravings and a zip code and nothing else, so a pick across town was exactly as likely as the place around the corner — and in Portland, where one neighborhood pool serves a whole cluster of zip codes, "nearby" could mean a twelve-mile drive. There is now a distance selector next to the zip field: Anywhere (the default, and exactly what you had before), or within 1, 5, or 10 miles. The radius trims the candidate pool before anything is matched, so it applies to Best match and Random alike, and a re-roll stays inside the distance you picked. Distances are straight-line from the center of your zip code — as the crow flies, which the picker says out loud rather than implying a driving estimate it can't make.
-
› a distance selector on the roulette form: Anywhere, 1, 5, or 10 miles
-
› the radius filters candidates before matching, so both selection modes obey it
-
› re-rolls stay within the radius the result was found at

Food Court introduces itself properly
The Food Court's first-run tour only ever talked about Restaurant Roulette — so landing on Recipe Finder or Meal Planner for the first time meant reading about craving picks and zip codes over the page you actually opened, and then never getting an introduction to it. Each sub-app now has its own tour: Recipe Finder explains cooking from your pantry and its near-miss matches, Meal Planner explains the reuse-driven week and its shopping list, and the hub introduces all three. Already dismissed the old Food Court tour? Nothing comes back.

The homepage finally says what Lab and Music Studio ship
Two cards on the homepage were describing apps that had outgrown them. The Lab card only ever mentioned Elixir, even though the Lab has spent months adding JavaScript, TypeScript, CPU and GPU sections — 25 lessons a visitor had no way of knowing were there. The Music Studio card only mentioned theory, sightreading and ear training, leaving out Cadence Keep (the tower-defense study game) and Maestro (sight-reading at a real MIDI piano) entirely. Both cards now name what the app actually covers.

Meal Planner now writes your shopping list
Generate a weekly plan and the shopping list comes with it — every ingredient the week needs, aggregated into one list and grouped by the same aisles the Recipe Finder picker uses (proteins, vegetables, pantry staples, dairy, herbs & spices). Nothing is listed twice: an ingredient six meals share is one line with a ×6 next to it, and a lunch built from last night's leftovers doesn't ask you to buy that chicken again. Change how many meals a day you're planning, or hit regenerate, and the list rewrites itself to match.

-
› deduplicated across the week, with a ×N count when several meals share an ingredient

Recipe Finder used to forget everything the moment you left — a returning cook had to re-tap their whole kitchen before getting a single suggestion.

A count and a Clear pantry button sit right above the search, so wiping the slate is one tap whenever your kitchen changes.

Food Court's second sub-app is here: Meal Planner generates a 7-day home-cooking plan optimized for ingredient and leftover reuse. Pick dinners only, lunch + dinner, or all three meals a day, then generate — every meal is composed to a 25% protein / 25% starch / 50% vegetables balanced plate, and cards call out when a meal reuses another day's leftovers (e.g. "uses leftover roast chicken from Monday"). Don't like the plan? Regenerate any time.

Every recipe card ships a photo of the finished dish, and picking one opens a detail view with have-vs-missing ingredients and full prep steps.

a new settings gear on every Music Studio section (Theory, Reading, Ear Training) lets you shuffle the order, control audio, set your session length, and turn on a timed mode that scales the pressure.
-
› shuffle cards to break out of the same review order
-
› control audio — mute the chord on reveal in Theory, or auto-play the prompt in Ear Training and Reading
-
› set how many cards a session draws so you can do a quick burst or a long sit
-
› optional timed mode with Slow / Medium / Fast countdowns — run out of time and the card counts as a miss

Cadence Keep: turn theory drills into a tower-defense game
Music Studio has a new optional game mode. Cadence Keep turns your theory flashcards into fast multiple-choice rounds that power a tower-defense battle — answer correctly to build your towers, slip up and the Dissonance marches on your keep.
-
› every theory card becomes a clear, self-contained question ("Spell the A dominant 7th chord") with four answer choices
-
› correct answers build and upgrade towers; wrong answers send tougher waves — combos and boss cards score big
-
› it's real study: answers feed your spaced-repetition schedule, with a casual mode if you'd rather just play
-
› lose a round and you get the exact cards that tripped you up, plus a "Defend again" rematch
