"Squeek Wheel Rush" is a free one-page browser game for the Squeekchain community. You play the hamster, Squeektoshi, running inside a giant wheel: the longer you stay on, the more points you earn and the harder it gets. Scores go onto a shared worldwide leaderboard. It is a community project, not made by the Squeekchain team (say so in small text on the start screen). Static site, vanilla JavaScript and canvas, no wallet connection, no keys, no transactions, works on phone and desktop.

LOOK: deep teal night room with a warm lamp glow, a large brass wheel, a cute orange cartoon hamster with a stuffed cheek, rounded heavy display font (Fredoka), big bold score. Polished and smooth, not generic.

WHAT EACH SCREEN SHOWS

1. Start screen: title "Squeek Wheel Rush", a "Start running" button, one line on how to play (tap or press Space to jump, hold to jump higher), the "Top runners worldwide" list (top 5 to 10), and the community disclaimer. The wheel turns slowly behind it with the hamster jogging.
2. Game screen: the hamster runs at the bottom INSIDE the wheel while sunflower seeds and red pegs ride the inner rim toward it along the curve. Big score at the top, the multiplier (x1.0 up to x12) and a timer under it, a mute button, and a status chip at the bottom centre that says "Squeektoshi is asleep" before a run and right after tripping, and "Squeektoshi is active" while running.
3. Game over screen: "Tripped!" or "New best!", final score, time on the wheel, best score, a name box (up to 14 characters) with a "Claim score" button that submits to the leaderboard and says "Claimed. You're #N in the world.", a "Run again" button, and the leaderboard with the player's new row highlighted.

HOW IT PLAYS: tap, click or press Space/Up/W to jump; holding jumps higher (variable jump). Jump over pegs, collect seeds, rare gold stars are worth a lot. Tripping on a peg ends the run (tumble animation, the wheel winds down). Points are never lost.

SCORING AND DIFFICULTY: score rises every second (10 x multiplier). Multiplier = 1 + seconds/12, capped at x12. Seed = 25 x multiplier, gold star = 150 x multiplier. Wheel speed ramps from about 1.5 to 2.8 rad/s and after 25 s surges slightly. Patterns unlock over time: seed lines, a single hop with a seed arc, pairs and triples of pegs close together, tall pegs needing a full-height jump, a gold star above a tall peg. Short rest gaps between patterns, shorter as time passes. Short synthesized sounds (jump, seed pitch rising with combo, gold arpeggio, thud on trip, soft footsteps) with a mute button and the M key.

SQUEEKCHAIN LINK: every 3 seconds GET https://api.squeekchain.com/v1/status (public, CORS enabled). If measurement.freshness is "online" and measurement.rpmMilli > 0, the real hamster is running: all points are worth 25% more and a small "+25% live wheel" note shows under the score. Never block play when the data is missing or the hamster is asleep.

SHARED LEADERBOARD (already set up, public by design): Supabase project URL https://baugveuujnzqsuehfrxz.supabase.co and publishable key sb_publishable_WruR0oYAecH4If6PT9uj2A_YOsjdQZP (send it only as the "apikey" header). Read the list with POST {url}/rest/v1/rpc/top_scores and JSON body {"n":20}; it returns [{name,score,secs}], best score per name. Claim a score with POST {url}/rest/v1/rpc/submit_score and body {"p_name":"...","p_score":int,"p_secs":int}; it returns {"rank":n,"name":"..."}. Errors come back as {"message":"slow_down"} (wait a few seconds and let the player retry), "bad_score" or "bad_time" (run rejected). Title the list "Top runners worldwide". Do not use any other backend and do not add accounts.
