Dead West

The Multiply symbol is a Special Feature that can only appear on the Feature Lane. When it falls onto an empty position on the reel below after an Avalanche, it activates its effect. The Multiply symbol has a random multiplier value of x2 or x3. Once triggered, it multiplies the value of all Hot Zone multipliers on its reel and on adjacent reels by its own multiplier. The feature ends after all applicable multipliers have been multiplied, and then a new Avalanche or spin begins.

The Expand symbol is a Special Feature that activates when it falls from the Feature Lane onto the reels after an Avalanche. When triggered, the position it lands on becomes a Hot Zone. If the position is already a Hot Zone, it is upgraded to an enhanced Hot Zone, highlighted with a fiery red frame, and its multiplier value is upgraded to the sum of all Hot Zone multipliers on the play area. If an upgraded Hot Zone is part of a winning combination, its multiplier increases by 1 at the end of the sequence before the next Avalanche begins. The feature ends once all upgrades are applied.

The Expand+ symbol is an enhanced version of the Expand feature and can only appear on the Feature Lane. When it falls onto the reels after an Avalanche, the landing position becomes a Hot Zone, and the Expand+ symbol also transforms itself and up to eight adjacent positions into Hot Zones. If Expand+ lands on or transforms a position that is already a Hot Zone, it upgrades it further. When a position reaches the persistent Hot Zone state, highlighted with a yellow frame, its multiplier is upgraded again to the sum of all surrounding Hot Zone multipliers. If a persistent Hot Zone is part of a winning combination, its multiplier increases by 1 and also adds the combined values of all adjacent multipliers to its final value before the next Avalanche begins. The feature ends when all applicable upgrades are completed.

The Bomb symbol is a Special Feature that activates when it falls from the Feature Lane onto an empty position on the reels after an Avalanche. When triggered, the Bomb explodes along with all symbols adjacent to its position. Scatter symbols, Wild symbols, Swap symbols, and unused multipliers are not affected by the explosion. After the Bomb symbol and all affected adjacent symbols are removed, the Bomb feature ends and a new Avalanche begins.

The Swap symbol is a Special Feature that activates after an Avalanche when it falls from the Feature Lane onto an empty position on the reels. Once triggered, it transforms itself and all adjacent symbols (excluding Scatter, Wild, Bomb, and unused multipliers) into the same type of symbol, forming a scattered win. If any of the transformed symbols are later changed again by another Swap feature, they become Wild symbols. The Swap feature ends once all transformations are complete. If the result created a winning combination, the affected symbols are removed and a new Avalanche begins.
