The player reads a race card, puts gold on a runner to Win or to Place, and watches the race run on a drawn garden course. Winnings go into the party’s gold.
The runners are racing snails. Every stable is generated from a seed: names, shell colour and pattern, silks and saddle cloth. Some runners like it damp and some like it dry, so the going changes who wins across the five garden courses.
The prices are measured. The bookmaker runs the same race model the player watches 2,000 times per card, so the house keeps its edge whichever runner is backed.
Three files, in order: DerbyCore.js, DerbyDraw.js, Derby.js. No image files. Code and graphics are AI generated, and the store page says so.
