Can anyone predict when the feature will land?
Symbols land on the 6x5 grid after every spin, and the bonus round can arrive on any of them. Nothing in the reel history shows when it comes next, so a long dry spell does not make it more likely. The result of one session is random whatever the RTP, because 96.50 is an average over a very large number of rounds. Set a budget before you start.
Each tumble refills the grid with new symbols, yet the RTP version that runs on this site appears only in the game rules, not on the reels. Open that panel before you start, so you know which figure applies to the spins you play.
Exploded spots turn into Multiplier Spots that double on each repeat hit, up to x128, and they clear once the tumble sequence ends. The maximum win is a ceiling reached very rarely, so treat it as the top of the table rather than an expected result. Plan each session around the bet you can afford, not around that ceiling.
