Boo Slot Overview

Are you ready for a ghostly adventure? Boo is a spooky, 4-reel online slot from Big Time Gaming, boasting 256 ways to win and a Halloween theme.

Symbols on the reels include low-paying card royals (9, 10, J, Q, K, A), while the high-paying ones feature green, blue, red, and purple ghosts. A multicoloured ghost serves as the Wild symbol, making its ghostly appearance on reels 2, 3, and 4—the Wild substitutes for all other symbols except the glowing jack-o’-lantern Scatter.

Boo Slot Features

Reactions

Each winning symbol, except for the Scatter, is part of a reaction and is replaced by a new Scatter, Ghost Symbol, or Wild. The chain of reactions continues, keeping the action alive until no more winning symbols appear.

Wild Symbol

Wilds substitute for every symbol except the Scatter symbol, and they only show up on reels 2, 3, and 4. Wilds can reveal Multipliers of up to x4 in the base game. When a Wild is part of a winning combination, the win gets boosted by the Wild’s Multiplier. If more than one Wild is involved in the win, each multiplier stacks for even bigger rewards.

Free Spins

Landing 3 or more Scatters on the reels triggers 12 Free Spins. As the Free Spins begin, the positions where the Scatters landed will get starting Multipliers of x2, x3, or x4. The rest of the grid kicks off with x1 Multipliers.

Multipliers only apply to Ghost symbols and Wilds. They are also persistent and can increase throughout the feature. Whenever you score a win with Ghost or Wild symbols, one or more of the winning positions will randomly have their Multiplier boosted by 1, 2, or 3. Plus, for every retrigger, the increment boost grows even more. During Free Spins, landing 3 or more Scatters awards an extra 3 Free Spins and upgrades the Multiplier on one of the grid positions.

Keep in mind, that once your total win hits that payout cap, the game round will automatically come to an end.
