PICK ONE

The engine ships as a browser module at https://danvid1009.github.io/gnarone-game-math/pick-one/api/rgs.js. It speaks the RGS provider contract (open, valid-bets, bet, next-action, collect; money in integer minor units; bet debits, collect credits) and rolls with crypto.getRandomValues in your page, so there is no server and every round is live. Pass seed to replay a round.

import { createGame } from 'https://danvid1009.github.io/gnarone-game-math/pick-one/api/rgs.js';

const g = createGame({ preset: 'coin' });                    // presets: coin, three, five, weighted
                                                       // bet types: OPTION_1, OPTION_2
const s = g.open();                                    // session, balance 100000, chipLevels [100,200,500,1000,2500,5000,10000]
const r = g.bet({ sessionId: s.sessionId, betAmount: 1000, betType: 'OPTION_2' });   // fresh crypto seed; win in r.totalWinAmount
g.collect({ roundId: r.roundId });                                           // credits the win → { balance }

// Replay any fixture: same seed, same code path, same answer as rounds/007.json
g.bet({ sessionId: s.sessionId, betAmount: 1000, betType: 'OPTION_2', seed: 'fixture-007' });

Seeds fixture-000 … fixture-099, served as plain JSON (GET, no auth, deterministic). Stake unit is 1000 minor units; scale linearly. The live module reproduces any of them when given the same seed.

One folder per preset: coin, three, five, weighted. Settlement rule is spelled out in each preset's field.json under how_to_settle; the same seed drives every preset, so round 007 has the same u in all of them.
