Aztec Clusters

Players can trigger the Wild Spin feature for 20x the bet size, guaranteeing at least 1 Wild symbol to dig up before the start of this spin.
The feature is available only during the base game.

‍

5+ same symbols dropping adjacent vertically or horizontally generate a winning cluster, pay, and disappear. After that, the empty spaces they left get filled with new symbols from above. This process keeps happening in the same spin until no more winning combinations are made.

A player can trigger the Free Spins round with either 0, 1, 2, or 3 guaranteed Sticky Wilds by purchasing it at x100, x200, x400, or x800 of the bet size.

3+ Scatters trigger 10 to 20 free spins and turn into Sticky Wilds or Cell Multipliers x10 for the Bonus game. The feature is retriggered if 3+ Scatters appear on the reels during the round.

Scatters can appear anywhere or be dug up within a Dig-up feature after a win. Each reel holds only 1 Scatter symbol, and having 3 Scatters on the board triggers 10 free spins, 4 – 12, 5 – 15, and 6 – 20.

A Destroyer can appear on empty cells after a win. It destroys all the low symbols without payment, disappears, and refills the field with new ones.

A Booster can appear on empty cells after a win. The symbol adds +2 to activated multiplier cells and +10 to any Wild on the board.

After a winning spin, Sticky Wilds can appear in empty cells, substituting for any symbol except Scatter, Booster, and Destroyer. If it lands on a marked cell with a multiplier, it obtains an additional x10 multiplier until the refill sequence ends. Its multiplier increases by x10 for each win it contributes to, up to a maximum of x100. 
In free spins, Wilds remain sticky until the round completes.

Winning clusters mark cells and add multipliers to them, starting at x2 and increasing by x2 with each new win on the same cell. The maximum multiplier is x10. Multipliers apply to all winnings in which they participate, with their values combined. Multipliers persist until the refill is complete and disappear on the next spin.
In the Free Spins round, marked cells and their multipliers last until the round ends.

After a winning cluster disappears, Bonus symbols may appear on the empty cells. There are four types of Bonus symbols: Scatter, Wild, Booster, and Destroyer.
