War by Evolution Gaming: headline RTP 96.56%.

Against our catalogue the number is above the median of 96.13%, higher than 87% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.
War has a published RTP of 96.56%, a house edge of 3.44%. We have not yet found a casino serving it at a different RTP build.
War is a Evolution Gaming game, so the outcome is produced by the studio's certified RNG rather than by the casino, and it is not provably fair in the cryptographic sense — you cannot recompute a spin from a seed. What the casino does control is which RTP build it serves. That is the real variable, and it is measurable.
