About Crystal Clusters

Crystal Clusters takes you underground, into a hidden world of shimmering stones waiting to be mined on a 7 × 7 grid. As groups of gems collapse and new ones fall in, the board quietly remembers the spots where your wins happened.

Inside Crystal Clusters

Five-gem clusters

Clusters need five or more identical symbols touching vertically or horizontally; they pay and then disappear. New symbols fill the empty spaces, and this keeps going inside one spin until no more winning clusters form.

Gem cells that remember

Every winning cluster marks its cells with a multiplier that grows with each new win on that spot. When several marked cells share a win their values are combined, and they hold until the refills finish, clearing on the next spin.

Scatters, one to a reel

Scatters can land anywhere, but never more than one on each reel. Three start 10 free spins, four give 12, five 15, six 20 and a full seven 30, and the same scale applies when they land again mid-round.

Crystal Clusters questions

What changes once the free spins begin?

Marked positions keep their values for the whole round instead of clearing, so the board can keep building from one free spin to the next.

Does a gem cell's multiplier count on the first win?

No, the first cluster only marks the spot. The next win landing there switches the multiplier on, and it doubles every time another cluster hits the same cell.

Is the mine's free spins round for sale?

The round can be bought: Buy Bonus starts Free Spins at the price shown in its pop-up, and that price adjusts when you change your play amount.
