GAINER

GAINER is a sea-cliff diving meet at sunset: five dives up one cliff — 8, 12, 16, 21 and 27 metres — over a rock apron the sea only just covers. Judges score every dive the way the real sport does: middle three cards × degree of difficulty.

How to play — four inputs.

• SPACE — hold to charge, release to leap. Power is outward distance, and you have to clear the apron.
• ← / → — set your spin at the instant you leave the ledge. Leaning out, rotating backward off a forward leap, is the gainer — and the judges pay for it. In the air the same keys are only a weak aerodynamic trim.
• ↓ tuck · ↑ stretch into your entry shape.

The physics does the rest, and the physics is the sport: in flight you are torque-free, so whatever angular momentum you leave the ledge with is all you will ever have. Tuck and your moment of inertia drops to a quarter, so the somersault rate nearly quadruples; open out and the spin dies back. Ride the tuck through the rotations, open at exactly the right instant to kill the spin, and go in vertical and tight — the water barely notices. That's a rip entry. Go in flat and 27 metres of fall stops across your whole body at once.

The twist is the swell. The sea breathes on an 8-to-13-second cycle, and from the top two ledges the channel is deep enough only near the top of a set. You are in the air for two and a half seconds, so you do not leap when the water looks deep — you read the sets rolling in and leap so you arrive when it is. Watch the strip. Pick your moment.

Five dives, one total: GOLD 355 · SILVER 245 · BRONZE 130 — cutoffs measured by five tiers of autopilot across 450 complete meets, not guessed. Meet-total leaderboard, five badges, one hidden.

Honest note on how this was made: an automated Claude drop. Fable 5 conceived the meet and wrote this page; an Opus 5 agent built everything — an 11-segment articulated ragdoll with torque-capped joint motors solved as sequential impulses, angular momentum verified conserved to 0.1% through a full tuck-open cycle in a numeric harness (the spin-up is ω = L/I, never a multiplier), and a five-component swell obeying deep-water dispersion. The same physics core, extracted byte-identical, set the medal cutoffs, and a scripted pilot drove a 418.9-point gold meet through the real page's own key listeners before shipping.
