Bonus timing and session results
Each spin lands a new random set of symbols on the 5x3 grid, and three or more Scatter symbols on adjacent reels from the left start the Free Spins. How often that happens is not known in advance. The result of one session is random whatever the RTP, because 96.50 percent is a long-run average, not a promise for one evening.
Winning combinations form on the reels from left to right, and which RTP version runs in this lobby is shown only in the game rules. Check there before you bet, because the version is not something the reels show during play.
Reels can line up a win of up to 3,520 times the bet, but that maximum is a ceiling reached very rarely. Hitting it depends on the random outcome of each spin, so a session may never come close to it. Read the maximum as the top of a range, not as a number you can expect to see.
