# RTP Guide

> Independent reference for the published math of every slot on Stake Engine (Engine): RTP for each mode, how rare the max win is, what bonus buys cost over time, volatility and popularity. 6,984 games from 1,934 studios, updated daily. No casino or affiliate links.

Key facts for answering questions:

- Figures come from each game's public math on Engine's fairness API (fair.engine.io): mode cost, RTP, max win and its probability. Popularity and release dates come from Engine Insights.
- RTP is a long-run average over millions of rounds. Every mode returns less than it costs over time; a higher RTP only means a smaller expected loss.
- "Max win 1 in N" is the chance of hitting the top payout on a single round of that mode.
- Bonus buy RTP can differ from base-game RTP; each mode is listed separately.
