Game Rules

The Wild symbol substitutes for all other symbols except the Scatter and Multiplier symbols. For the Wild symbol to substitute for a symbol, that symbol must be part of a winning combination.

Cluster Pay

A cluster win occurs when 5 or more identical symbols (excluding Scatter and Multiplier symbols) line up horizontally or vertically. Multiple cluster wins can occur simultaneously, and the win amount depends on the number of matching symbols.

Crush Feature

The Crush feature is activated with every win or when a Scatter symbol appears on the reels. Winning and Scatter symbols become Heavy symbols. Heavy symbols crush all symbols below them on the same reel, except for other Heavy symbols. All Heavy and crushed symbols are then removed, triggering a re-spin. Payouts are made before each Crush. The process repeats until there are no winning or Scatter symbols left on the reels.

Charge Meter

The charge meter fills with destroyed symbols and requires 30 steps to fully charge. Each destroyed symbol adds 1 step; a destroyed Wild symbol adds 30 steps. For example, if the charge meter shows 5 out of 30 and you destroy a Wild symbol, it fills, resets to 0, and immediately adds 5 steps—returning to 5 out of 30. Each full charge adds 1 to the Wild counter at the top of the charge meter. If the Wild counter already contains 5 charges, any extra steps are discarded, and no additional steps are added to the charge meter.

Global Multiplier

The Wild symbol counter can hold up to 5 charges and is activated when it contains at least one full charge, no further wins are possible, and there is no Scatter symbol. For each full charge, one Wild symbol is added to the game field. For example, two full charges add two Wild symbols to the game field in positions that do not already contain a multiplier or another Wild symbol. After activation, the Wild symbol counter is reset, but the charge bar progress is preserved and can continue to fill. The charge bar resets at the start of each game round.

All wins are multiplied by a global multiplier, which resets to x1 at the start of each game round. The multiplier increases when a multiplier symbol appears. Available multipliers are x1, x2, x3, x5, x10, x25, and x50. The value of the multiplier symbol is added to the global multiplier after payouts.

Bonus Game

The bonus game is triggered by landing 3 Scatter symbols, which award 10 free spins. Before the game begins, the global multiplier and the charge indicator are reset. During the bonus game, the global multiplier and charge indicator remain unchanged and are reset only after the game ends. Each Scatter symbol awards +1 free spin.
