An illustrative table, not a released game. Every REVRA title is specified this way first: the outcomes, their exact probabilities, and the return they add up to. Bar heights use a square-root scale so the rare outcomes stay visible.

Instant games

Short rounds built on one clear idea: a ladder you can leave at any step, an urn that changes as you draw, a chain reaction across a grid.

Slots

Ways and line games built from explicit reel strips and paytables, in HTML5 Canvas with synthesised audio.

The model comes first

Fourteen playable prototypes, with design targets from 95.70% to 97.00% return. The games make no third-party requests and need no plug-ins.

The games shown to partners are demonstrations that run on virtual credits. They are not certified for real-money play, and no deposit can be made on this site.

Privacy: when you sign in with an invitation link, we record the sign-in and which demos you open, under the partner name on your link, to follow up on your evaluation. Those records are kept for up to 90 days. This site sets one sign-in cookie and nothing else, and uses no third-party trackers.
