About this Slot
Reef Rumble from Dahlia has an RTP of 96.3%, medium volatility and a maximum win of 10,000x.
Winning combinations form when eight or more identical symbols land anywhere on the grid. Winning symbols then disappear and new symbols cascade down to fill the empty spaces.
During free spins, each cascade increases a multiplier by one, starting from 1x at the beginning of each free spin round. Random multiplier symbols also appear during the bonus round to enhance payouts.
Three or more scatter symbols trigger free spins, with the number of scatters determining how many free spins are awarded. Extra scatters that land during the bonus round retrigger additional spins.
Boost mode increases the chance of triggering free spins by a factor of ten and remains active until manually disabled.
A bonus buy option is available to start the free spins round immediately.
