Slots With the Biggest RTP Gap Between Casinos in 2026
Every figure below was read from the in-game help screen at each casino. These are not estimates - they are the exact RTP that each casino has configured for each of their games. On Le Bandit, the gap between the best and worst casino is 4.17%.
Casinos legally choose the RTP with which to run each of their slots games. The same game will pay out at 92% at one casino, yet 96% at another - most players unaware of this will lose an extra £4.17 for every £100 wagered at the wrong casino. In the following list, we check every slot game at each of the 10 casinos and detail the RTP at every location.
