What Raiden Shogun cannot tell you before you play
The bonus round arrives without warning. No sequence of results predicts when the next Free Games will trigger, and no bet size, feature purchase, or RTP version changes that. Every session outcome depends on pure chance; a run of base-game spins tells you nothing about what comes next.
Three RTP versions run across different machines: 96.62%, 96.64%, and 96.67%. Which one powers the game you're playing appears only in the rules section of that machine. You cannot choose the version from outside.
Raiden Shogun's maximum win exists as a ceiling you could theoretically reach, but sessions that climb that high are extraordinarily rare. The figure describes a boundary, not something to expect or plan around.
