Kluster Krystals Megaclusters Bonus Features

Symbol Upgrades:

If you land a winning cluster on the reels, it may cause an upgrade to be added to the reels. These upgrades come in four different forms. These symbols will be upgraded when they appear next to the winning cluster and come in the forms of singles, double, triples and quadruples.


Multipliers land with up to 10x as their base multiplier and can be upgraded up to three times. To upgrade a multiplier, players must land a winning cluster next to the base multiplier. The multiplier will increase by the multiplier’s base value, meaning that your x10 multiplier could increase up to x40.

Free Spins

If players manage to upgrade one of their bonus symbols fully, it will provide them with seven Free Spins. Players can land any of the additional bonuses in this round and they can re-trigger their Free Spins by fully upgrading a bonus symbol in the bonus round.
