Club Tropicana bonus timing is not known in advance
Three, four or five SCATTER symbols anywhere on the reels start the Free Spins, and nobody can tell in advance how often that happens. Each spin is a fresh result, so a quiet stretch or a busy one tells you nothing about the next spin. The RTP version sets the long-run return, while the outcome of one session stays random.
Symbols land across the 5x4 grid on every spin, but the RTP version that Surge Casino runs is shown only in the game rules. Check that section before you play, because the two versions return slightly different amounts over time.
Winning combinations on the 12 paylines can add up, but the maximum win is a ceiling that very few spins reach. The figure is a multiple of your bet, so a bigger stake raises the money ceiling in step. Treat the ceiling as a rare target, not an expected result.
