Wheel mechanics, grouped and live.

Each page collects a family of mechanics as live, replayable demos, with the minimum code that makes each one work.

Start here

A wheel in ten lines, the gamble wheel, and a template round-tripped through JSON.

A wheel in ten lines, the two-colour gamble, and a template round-tripped through JSON.

Stopping

Where the pointer ends up: exact angles, centring, bounce, skip.

Where the pointer ends up - centre, random, an exact offset or angle - and what happens after it lands.

Anticipation

Near-misses that bait the player: creep, stutter, stall, protected skips.

Bait the player with one section and land on another - creep, stutter, stall, and a tease that survives a skip.

Sections, rings and states

Dynamic sectors that move, rings that spin each other, a wheel idling under the reels.

Sector shares that move step by step, an inner ring spun by the outer one, and a wheel that idles under the reels.

Skins and assets

Every layer of disc art, the tongue end to end, and three production wheels with their studios' own assets.

Every piece of art a wheel face is made of, what each one has to match, and the code that mounts it.

The pointer end to end - where it sits, the pegs it rides, elasticity, friction, drag, its art, its events and its sounds.

Per-section styles and three production wheels built from their studios' own art.

Server, events and debugging

Adapters for real responses, sound hooks, the debug view.
