The Guides section is the theory layer of 100RTP.games. Game audits show how specific Originals work. Tools calculate exact numbers. Casino reviews compare platforms. Guides explain the underlying ideas: what 100% RTP means, how zero-edge gambling can be implemented, why fair games still carry risk, how allowance systems work, and why provably fair verification is not the same as RTP proof.
Use this hub as the main learning path for zero-edge casino math. The pages are grouped by topic so you can move from basic concepts to more technical verification.
Editorial standard: We separate mathematical return, provably fair verification and platform risk. A game can be provably fair but still have a house edge. A game can advertise 100% RTP but still have caps, variance and withdrawal risk.

- Allowance: the eligible wager volume where fair or near-fair pricing applies.
- Rakeback: a partial refund of theoretical or actual cost after play.
