GAME OF THREE

GO3 / Rock n Smash. Three rocks; a fixed table says how many break (0–3) and pays 5 / 1 / 0.5 / 0; on 2 or 3 a gem fires with a fixed chance and multiplies by 2–10× from a weighted table. RTP is the exact sum over 16 outcomes: 97.07% base, 97.15% boosted. Reproduces Rock n Smash.xlsx.

Live API (browser module)

The engine is published as an ES module that implements the RGS provider contract and rolls locally with crypto.getRandomValues: open, valid-bets, bet, collect, with the observed balance semantics (bet debits the stake, collect credits the win, integer minor units). No server, every round live, and any round replays from its seed. Bet types: BASE, BOOSTED.

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

const g = createGame({ preset: 'sheet' });                   // presets: sheet, rtp-0.95
                                                       // bet types: BASE, BOOSTED
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: 'BOOSTED' });   // 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: 'BOOSTED', seed: 'fixture-007' });

Presets and static fixtures

Presets: sheet, rtp-0.95 (default sheet). Each preset is a frozen configuration and its own folder: the config, derived tables and settlement rule in field.json, plus one hundred pre-drawn rounds from seeds fixture-000 … fixture-099 settled for every bet type. The same seed drives every preset, so round 007 uses the same u everywhere, and the live module reproduces any of them when given the seed.
