Slot mathematics

What is included

• Game mathematics. Paytable, reels or outcome tables, feature logic and weights designed to your targets: RTP, hit frequency, bonus frequency, volatility, max win.
• PAR sheet. Every metric with the simulation it comes from: rounds, seed, confidence interval. Base game, bonus and every bet mode separately.
• Simulation. Acceptance runs of hundreds of millions of rounds per mode, sized so that the result is inside the tolerance you name.
• RTP profiles. Several RTP versions from one model — the lever changes the bonus value, not the feel of the base game.
• Certification documents. Game rules, math description and simulation reports in a form your lab expects.
• Playable viewer. Every version comes with a round viewer: replay any round by seed, look at bonuses, check the distribution by eye.

Timing

A typical new slot takes two to four weeks from brief to first draft, and one to two weeks of iterations after that. A new RTP version of an existing model usually takes days. We name the dates after reading the brief.

How we work

1. Brief. Your GDD, a reference game or a short description: grid, features, bet modes, target numbers.
2. Draft. A first model with its PAR sheet and a playable viewer, so you judge the feel and not only the table.
3. Iterations. You say what feels wrong; we change one lever at a time and show what moved.
4. Package. Config in your format, engine source, PAR sheet, reports and documents — one versioned link.

We do not publish prices on the site: scope differs a lot between a single RTP version and a full slot. Send a brief and we answer with scope, timing and cost.
