The treasure trove of Krystals has more to serve up, with 3 mini-features that are guaranteed to trigger after a sequence of 6 avalanches. Krystal Vanish will pick one symbol group based on colour and wipe them from the game area. Krystal Boost will upgrade all visible normal symbols, while Krystal Kut will remove all visible, single, normal symbols.

When a Bonus symbol lands near a winning cluster and gets upgraded to a quad symbol, players are taken to a fully-charged Free Spin round, bringing 7 free spins. Quad Bonus symbols in Free Spins re-trigger the round’s benefits, bringing 7 free spins and an additional 4! With symbol upgrades hidden in every nook and cranny, Kluster Krystals brings winners together for maximum thrills and magnetic wins.
