Before the first turn, nothing is certain
Four or more SCATTER symbols anywhere on the grid start the bonus round, yet nobody can tell in advance how often those symbols will land. The result of one session is random, whatever the RTP. A short session may bring no bonus at all, and a long one may bring several. Past spins do not change what the next spin brings.
Every spin on the 6x5 grid counts toward the RTP of the version in use, and that version appears only in the game rules. Open the game rules before you play to read which version is in use, and keep that version in mind when you compare the figures in the table.
Tumbles on the grid and multiplier orbs can lift one round far above its stake, but the maximum win of x50,000 the bet is a ceiling that is reached very rarely. No one can predict when, or whether, a session comes near it. Treat the maximum win as a figure on the paytable, not as a result to expect.
