6 Jokers Gives No Forecast of Feature Timing
Reels stop at random after every spin, so how often the bonus round comes is not known in advance. The result of one session is random whatever the RTP, and a return that averages out over many spins says nothing about a single session.
Reels follow the RTP version set for this game on this site, and that choice appears only in the game rules. Read the rules before the first spin, so the figure in the table is matched to the version actually in use.
Reels reach the maximum win of 6 Jokers very rarely. That ceiling is a multiple of the bet, and the game promises no spin or session that comes close to it. Read the ceiling as the upper limit of the game, not as an expected result.
