Limits of Bonus Timing and Session Results
Scatter symbols land at random on the 6x5 grid, so the Free Spins bonus round can start on the first spin or after many spins without one. No one can predict how often that happens. The result of one session is random too, and the RTP figure describes a long-run average, not what a single session will return.
Each spin pays out under one RTP version, and the version live in Betbolt's lobby is shown only in the game rules. Open that panel before the first spin to see which rate applies to the game you are playing.
Tumbles and Multiplier bombs can stack into a large Free Spins win, but the maximum win of x25,000 the bet is a ceiling that a round reaches very rarely. Nothing on the reels promises that a session will come near it.
