Thirty symbols drop onto a six-by-five screen. Eight or more of the same symbol anywhere on it pay, then they burst, the rest fall, and new ones drop in: the wins keep tumbling for as long as they come. Multiplier orbs (2x to 500x) stay on the screen, and when the tumbles end with a win they're added up and multiply it.

Four or more scatters start 15 free spins, where every orb that lands on a winning spin adds to a multiplier that lasts the whole round, and three more scatters give 5 more spins. Or buy the free spins straight away for 100x the bet.

It returns 94.5% of everything bet over time. Every theme is the same machine with its own pictures, as on real slots. Each spin comes from your own provably fair seed pair the moment your bet is placed, and is decided in full there. Check any spin on the Provably fair page.
