Game Rules

Wild symbols. Wild symbols appear only during the Sidewinder Shuffle feature. They substitute for all symbols except the Mystery and X symbols.

Super Wild symbols. Super Wild symbols appear only during the Sidewinder Shuffle feature as a single stacked symbol. They act like regular Wild symbols across all three reel positions, substituting for all symbols.

Mega Wild symbols. Mega Wild symbols appear only during the Sidewinder Shuffle feature as a single stacked symbol. They act as regular Wild symbols across all three reel positions and trigger a win multiplier (x2, x3, or x5).
For example, if after a shuffle there’s a 1.00 line win that includes a x5 Mega Wild symbol, and the multiplier bar is at x10, the payout will be: 1.00 x 5 x 10 = 50.00.

Mystery Symbols

Mystery Symbols can appear during the base game, depicted as a pair of shutters. All Mystery Symbols on the screen open to reveal one of the paytable symbols.

Mystery Symbols can also appear in the same game where the Sidewinder Shuffle feature is activated. If this occurs, the Mystery Symbols are included in the feature and will be revealed after each shuffle. Up to three Mystery Symbols can appear on each reel during each spin.

X Symbols

X symbols can appear in the base game, superimposed on regular symbols. Each X symbol that appears adds one step to the Sidewinder multiplier bar. The bar remains at this position (unless additional X symbols appear) until the next Sidewinder Shuffle feature is activated.

Up to 3 X symbols can appear between each Sidewinder feature, increasing the starting multiplier bar to x4.

Sidewinder Shuffle function

The Sidewinder Shuffle feature is activated in the base game when 5 spheres light up above the reels. (0 to 5 spheres will light up during each spin of the base game.)

The reels are shuffled until a winning combination is formed. After the first win, the reels are shuffled again. If the shuffle results in a winning combination, the feature continues; if it results in a losing combination, the feature ends. A win multiplier is applied to each win awarded during the feature. The multiplier scale starts at x1 and increases with each increment. Possible multipliers are: x1, x2, x3, x4, x5, x6, x8, x10, x12, x15, x20, x30, x40, x50, x100, x150, x200, x250, x500, x1000, x2000. With each winning shuffle, the multiplier scale increases by one increment. Each win during the feature is multiplied by the current win multiplier. At the start of the feature, up to 6 Wild, Super Wild, Mega Wild, or Boost symbols are added to random spots on the multiplier bar. If the bar increases to a position containing one of these symbols, a Wild/Super Wild/Mega Wild symbol is added to a random reel before the next shuffle; or if a Boost symbol is awarded, all random symbols on the reels are upgraded to the same random symbol of a higher level.

The feature is played with the same base bet as the triggering game. The multiplier bar resets to 1x after the feature. The Sidewinder Shuffle feature cannot be retriggered.

Xtra Power – Progress Bar

The progress bar advances when four spheres light up during a spin.

When four spheres light up, the progress bar advances by a randomly determined number of steps. The progress bar starts at X1 and can advance between 1 and 15 steps. The advance value is determined using a weighted random process, where the possible advance values ​​and their probability distribution depend on the current progress bar fill level. When the progress bar is full, the next Sidewinder feature activated is the Xtra Power feature.

After the Xtra Power feature is played, the progress bar resets to a randomly determined position and begins filling again.

Xtra Power Feature

Each of the 5 activating spheres will show either 1, 2, or 3 and increase the Sidewinder multiplier meter by that amount. The Sidewinder multiplier meter then starts from this increased state during the Sidewinder Shuffle feature.

The Xtra Power boost is awarded in addition to any previous meter boosts from X symbols.

The progress bar and any multiplier bar boost from X symbols are persistent, and any progress will be saved for each individual bet and game mode.
