Big Bass – Hold & Spinner has no fixed timing
5x3 grid, 10 paylines, and still no way to know when the bonus arrives. How often Free Spins or Hold & Spinner come is not known in advance. The result of one session is random, whatever the RTP. An RTP describes the long run, not the next session.
96.07 or 96.09 is the RTP version in play, and only the game rules show which one applies. Read them before your first spin, since the two versions pay differently over time. Both figures sit close together, but close is still a difference on paper.
x10,000 is the ceiling: the highest multiple of the bet this slot pays. At the top example bet of A$2, that ceiling is A$20,000. It is reached very rarely, so treat it as a ceiling, not a target.
