Game Rules

This is the WILD symbol and substitutes for all symbols except the SCATTER symbol. It appears on all reels.

Expanding Wilds with Multiplier

These are EXPANDING WILD symbols.

They appear on all reels.

When any of them lands in the main game or during FREE SPINS, if a win would result from the expansion, it expands the entire reel vertically and receives a random multiplier.
Possible values: 2x, 3x, 4x, 5x, 6x, 7x, 8x, 9x, 10x, 15x, 20x, 25x, 50x, 100x, 250x, 500x, or 1000x.
The multiplier is applied to all winning combinations of which it is a part. If more than one WILD symbol is part of a winning combination, their multipliers are added together.

Free Spins

These are SCATTER symbols.

Look for 3, 4, or 5 SCATTER symbols to trigger the FREE SPINS feature and win 6 free spins with a minimum random multiplier for EXPANDING WILD symbols landing during the round of 2x, 4x, or 8x, respectively.

Before the round starts, you can gamble to increase the minimum multiplier for EXPANDING WILD SYMBOLS in the next round, or claim the current value and start the round.

When you gamble, the wheel spins and stops on either a win or a loss. If it lands on a win, the current minimum multiplier moves to the next higher value in the list of possible values. If it lands on a loss, all free spins are lost and
the round ends. You can only gamble up to the minimum multiplier of 100x. The chance of winning with each gamble is displayed in the game under the wheel for each gamble step.

The FREE SPINS round begins when you claim the current minimum multiplier or when the maximum is reached.

During a round, all EXPANDING WILD symbols are also MOVING WILD. This means that when they land, they expand, a random multiplier is selected, and then the game performs respins until the MOVING WILD symbols move one reel to the left on each respin, returning to reel 1, maintaining the same multiplier that was randomly determined when they landed. Once a MOVING WILD reaches reel 1, it moves off the grid, and respins are no longer activated for that symbol. If multiple EXPANDING WILD symbols appear on the screen at the same time, the respins end when all of them leave the screen.

Land 3, 4, or 5 Scatter symbols during the round to re-trigger the feature and win 6 additional free spins. Each re-trigger increases the minimum multiplier by 1, 2, or 3 positions from the current value for landing 3, 4, or 5 Scatter symbols. If the minimum multiplier reaches 1000x, subsequent re-triggers do not increase the minimum and award only 6 additional free spins. Special reels are included in the game.
