Boo is a Halloween-themed video slot that was developed by Big Time Gaming and released in September 2024. The game is set in a misty graveyard filled with pumpkins, which you must attempt to survive.
Symbols in the Boo slot include purple, red, blue, and green ghosts, as well as stylised playing card icons, rainbow wild ghosts, scatter pumpkins, and more.
The Boo slot is played on a 4×4 grid layout with 256 paylines. You’ll need to bet between £0.10 and £20 per spin, and the game gives you a chance to win up to 47,050x your bet, which is huge. To make wins, you need to match three or more identical icons on a single spin and payline.
The highest-paying symbol in the Boo slot is the purple ghost, which pays 0.4x your bet for landing three times and 2x for landing four times. After this, the red ghost pays 1x, the blue ghost pays 0.9x, the green ghost pays 0.8x, Aces and Kings pay 0.4x, Queens and Jacks pay 0.3x, and 10s and 9s pay 0.2x your bet.
The Boo slot comes with a return to player (RTP) rate of 96.54%, which is around the average for most video slots. The RTP tells you how much of all wagered funds are returned to you over a long time. Meanwhile, the video slot comes with high volatility, so you can expect to make larger but infrequent wins when playing.
The Boo slot comes with winning reactions, where all winning symbols except for scatter icons are removed from the reels and replaced by scatter, ghost, or wild icons.
Wild symbols substitute for all symbols except for scatter icons, and they can only appear on the second to fourth reels of the grid. In the base game, wild icons can reveal a multiplier of up to 4x, and wins are multiplied by the displayed multiplier for each wild icon that substitutes in the win.
Landing three or more scatter icons in any position awards 12 free spins. Each of the 16 on-screen positions has a multiplier in the feature that persists and can increase. Whenever there is a win with ghost symbols or wild icons, one or more winning positions will have their multiplier increased.
During the free spins mode, three or more scatter icons award three more free spins and increase the multiplier on the same positions. These multipliers only apply to ghost and wild symbols.
There are several games similar to the Boo slot, all of which use a Halloween or spooky theme. One game is Halloween by Games Global, which is based on the popular film of the same name. It uses a 5×3 grid layout with 50 paylines and a 96.01% RTP. Symbols here include knives, telephones, clown masks, and characters from the film. Feature-wise, the game comes with wild icons, cash prizes, free spins, and multipliers.

It also comes with special features like moving wild icons, free spins, stacked symbols, expanding icons, and more.
The Boo slot is a fun online casino game from Big Time Gaming that takes a very common theme and elevates it with gorgeous visuals and special features in an effort to create something unique and memorable. All of this is perfect for high-rollers and experienced players, but we suggest new and returning customers try something different.
