Cluster Cup by Caleta Gaming: headline RTP 93.45%.
An RTP of 93.45% means a house edge of 6.55% — the expected cost is 6.55 units per 100 staked over the long run, whatever a single session does.
Against our catalogue the number is below the median of 96.13%, higher than 2% of the games whose RTP we verified. That comparison matters more than the raw figure, because "96%" only sounds generous next to nothing.

Cluster Cup is a Caleta 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.
