Flagship demo: Summit Gold

5x3, 20 lines, high volatility. Free spins with multiplier wilds (x2 and x3) that multiply along a payline up to x27, retriggers, bonus buy at 91x. Runs on desktop and mobile, portrait and landscape.

Demo, play money only. No real-money play, no deposits, no prizes, no payouts. GC and SC in the demo are units without value. The demo is a showcase for operators (B2B). 18+. Keyboard: open the demo full screen and press Space to spin.

  • Vector-drawn art, no stock or AI asset dumps. One consistent visual language you can extend into a series.
  • Client only renders. Outcomes come from the shared math engine, server-side in production.
  • Gold Coin / Sweeps Coin toggle built in: two ledgers, one math model.
  • Turbo, autoplay and paytable in the client; reality-check timer and forced-result test mode in the reference RGS.

The math is the product

Graphics get a game noticed. The math is what a test lab reviews and what decides how a game plays. We design the reel strips, paytable and feature logic as code, then check every number with a Monte-Carlo simulation that can be reproduced from the seed.

PAR SHEET

RTP with confidence interval

100,000,000 rounds in about one minute on a single machine (reference run: 60.2 s). RTP, base/feature split, hit frequency, volatility index, feature frequency, feature win percentiles, max win, full win distribution.

RTP VARIANTS

One model, several RTPs on request

Reel-strip variants for different target RTPs (for example 94 / 96 / 97%), each simulated and documented separately. Summit Gold currently has one RTP (96.4% target).

RNG

Documented randomness

OS CSPRNG in production, seeded xoshiro128** for reproducible simulations, rejection sampling for unbiased reel stops. Documented seeding methodology.

RGS

Reference integration

Seamless-wallet flow with idempotent rounds, bet / win / rollback ledger, GC / SC dual currency, reality-check timer, forced-outcome test endpoints. Built to be adapted to the operator's wallet API.
