Crypto Casinos' Secret Menu: How RTP Figures Vary by Operator

Crypto casinos have a secret menu when it comes to return-to-player (RTP) figures. The RTP figure is not a property of the slot game itself, but rather a choice made by the casino's staff.

This means that different operators can offer the same game with varying RTP figures. For example, Starburst has been certified at 90.10%, 92.13%, 94.10%, and 96.09%.

The decision on which RTP figure to use is driven by four main factors: tax and duty, market positioning, jurisdiction floors, and commercial terms with the studio.

One of the key drivers is tax and duty. In April 2026, the UK Remote Gaming Duty rose from 21% to 40% of gross gaming revenue. This led to operators shifting their standard slot configuration down a notch or two, from the 96% band toward 94%, with negotiations reportedly bottoming out around 92%.

Dexsport is an example of an operator that licenses its entire catalogue and runs no in-house originals. This means that every return figure across its lobby is a studio build the platform selected, with no house-built alternative sitting alongside it at 99%.
