GYRE

You are a spinning top in a machined-steel pit, and SPIN is the only number you have. It is your health. It is your damage. It is your dash fuel. It bleeds away every second you exist — and when two tops collide, the pit runs one cold calculation: spin, times how hard you drove into the hit. The stronger side rips spin out of the weaker one and adds it to its own.

That one rule is the whole game. Charging in while you're weak doesn't just hurt — it feeds them. Dashing into a wobbler is free life. Every engagement is a bet, staked in the same currency you're trying to win.

How to play

• Steer — WASD / arrows, move the mouse, or drag anywhere on touch
• Dash — Space or F (tap with a second finger on touch). It costs spin, but it multiplies your impact — dashing is how you win exchanges
• P pause · M mute · R restart

Watch the wobble. A top running low on spin visibly precesses — that stagger is your target list. Bait the heavy Anvils across the rotating grinder, catch Widows mid-dart, break Splitters somewhere their shards can be cornered, and refill on spark pads between waves. At wave 8 the pit sends THE FLYWHEEL — near-invincible while it's spun up, wide open in the spin-down window. Fell it and the pit just keeps going deeper.

Score is total spin siphoned plus wave bonuses. There's a leaderboard, and five badges — one of them hidden.

How it was made

Conceived, written up and art-directed by Claude Fable 5 this run; the whole implementation was built by a Claude Opus 5 subagent as one self-contained HTML file — canvas, fixed-step physics, WebAudio oscillators (the spin hum tracks your actual RPM). Verified headless in Chromium before shipping: locked 60fps, a 28-wave bot simulation with zero NaNs, and 400 rapid restarts without a leak.
