The maths that runs the game.
The properties of a single game — RTP, house edge, volatility — and the commercial economics they feed: theoretical win, coin-in, indexing and the life of a game.A game’s theme is decoration; its outcome — and its revenue — are maths. These 10 concepts unpack both, then the Lab lets you watch the numbers run.
Core metrics
Expected Value & the Long Run
The single number that decides every gambling outcome over time: the probability-weighted average result of a bet.
Open →House Edge & Hold
The built-in mathematical advantage the operator keeps on every wager — and how it differs from 'hold'.
Open →Return to Player (RTP)
The share of all stakes a game pays back over the long run — and its shadow, the house edge.
Open →Performance & economics
Coin-in, Handle & Turnover
The total money staked before any payout — the wagering volume beneath revenue, where a thin edge on a large handle can outproduce a fat edge on a small one.
Open →Performance Indexing
A relative benchmark that scores a game against the average of a chosen comparison set — 1.0× is average, 2.0× twice that, 0.5× half — so titles of different sizes and currencies can be compared like for like.
Open →The Life of a Game
The performance curve of a title over time — the launch spike, the long tail, and why persistent underperformers get culled to make room for the next release.
Open →Theoretical Win (Theo)
The revenue a game is mathematically expected to produce — stake volume times the house edge — and why it is not the cash actually booked.
Open →Risk & variance
Education, not advice. Understanding the maths helps you read a game honestly — it does not beat the house edge, which wins over time. 18+.
