Boo is a new slot from Big Time Gaming due for release in September 2024, in time for the Halloween holidays. Boo promises a fun-filled experience featuring cheeky ghosts and pumpkins set in an eerie graveyard. Big Time Gaming is known for flair and innovation in slot design, and Boo is another fine example of the talented team behind BTG.

About Boo

Boo features a comedy-style Halloween theme set in a graveyard with mist swirling around the gravestones. The reels sit in the middle of the screen, and a dimly lit haunted house can be seen in the background. It’s a vibrant and atmospheric slot, capturing the essence of Halloween.

The lower paying symbols are the royal card suits and 4 matching awards 0.2x to 0.4x the bet. The green, purple, red and blue ghosts represent the high-paying symbols, and 4 matching symbols on a spin award 0.8x to 2x the bet. The multicoloured ghost is the Wild, which comes with multipliers but only appears on reels 2, 3 and 4. The creepy pumpkin is the Scatter.

Boo has a 4×4 grid with 256 ways to win. It’s available to play on desktop and mobile devices from 10p to £20 per spin. There are two RTPs with the default 96.54%, but some operators have the option of 94%. Boo is highly volatile, with a max win of 47,050x the bet.

Gameplay and Features

The features in Boo are not in abundance, but they do pack a punch. These include Wild Multipliers, Cascading Reels, and a Free Spins round.

Wild Multipliers

The Wild symbol is the multicoloured ghost and only appears on reels 2, 3, and 4. The Wild is a substitute for all symbols except the Scatter and has multipliers up to 4x, which are awarded to all wins involved. If multiple Wilds contribute to a win, their values are multiplied, and a payout is awarded.

Reaction

The Reaction triggers after a winning combination, and all symbols involved explode and are replaced with new symbols. This can lead to multiple wins on a single spin. The Reactions continue until no new wins occur.

Free Spins

If 3 or more Scatters land on a spin, the Free Spins bonus triggers, awarding 12 free spins. This feature can be retriggered with 3 or more Scatters for an additional 3 spins.

Each position on the reels has a multiplier value during the Free Spins. If a win occurs with high-paying symbols or Wilds in a free spin, 1 or more positions will have its multiplier increased by +1, +2, or +3.  Multipliers are only applied to high-paying symbols or Wilds, and each win is multiplied by the multipliers on all high-paying symbols or the Wilds.

Players can buy into the Free Spins for 90x the bet for 12 free spins or 500x the bet for 24 free spins.

Conclusion

Boo, developed by Big Time Gaming, is a fun slot that looks set to become a firm favourite among slot enthusiasts and fans of Halloween. With atmospheric graphics, immersive features, and a win potential of up to 47,050x the bet, it delivers a visually appealing and potentially lucrative experience.
