Boo (Big Time Gaming) – Review & Demo Play

The Boo Slot Game

A misty graveyard sets the tone in Boo, with carved pumpkins glowing and friendly phantoms drifting across a compact 4x4 grid. Under the hood it’s anything but cosy. You get 256 ways to win, wins pay left to right, and a reaction system clears winning symbols so new ones drop in. The base game can feel measured, yet wilds can flip in with multipliers, while the bonus round is where the slot stretches its legs thanks to sticky position multipliers.

Symbols and Payouts in Boo

Low pays are the shiny 9–A royals and they need four of a kind to score. Four-of-a-kind royal hits return 0.2x to 0.4x the stake. The high tier is a set of green, blue, crimson, and purple Ghosts that pay on three or four. Four Ghosts in a way pay 0.8x to 2x, while three-of-a-kind Ghost wins sit in the 0.1x to 0.4x band. Wins start from the leftmost reel and must land on consecutive reels.

Pumpkin Scatters trigger features and are not affected by reactions. Rainbow Ghost wilds land on reels 2, 3, and 4, substituting for regular pays. In the base game, any wild used in a win may reveal a multiplier up to x4, and multiple wild multipliers stack into the same win. All listed prizes are applied to the total bet. The reaction system removes winning symbols, then drops new ones, giving rolling chances to line up fresh combinations.

The Boo Slot Bonus Features

Boo keeps the feature list tight, with reactions, multiplier wilds, free spins, and a paid entry to the bonus. Reactions trigger after every winning tumble, clearing the pays and letting new symbols fall. In the base game, wilds can flip over with x2–x4 attached, and if more than one wild helps, the multipliers are applied together. That can perk up the measured base, though the real fireworks arrive once the pumpkins open the door to free spins.

Hit three or more pumpkin Scatters and you get 12 free spins. Every grid position carries a persistent multiplier that lasts for the whole feature; positions that held the triggering Scatters can start at x2, x3, or x4, while all others begin on x1. When an initial free spin lands a win with a Ghost symbol or a wild, one or more winning positions increase by a random +1, +2, or +3. Retriggers add +3 spins and boost a position as well.

Multipliers only apply to Ghosts and wilds, and each Ghost or wild in a win is multiplied by the value under its position. If patience isn’t your thing, the Feature Buy offers 12 spins for 90x the stake, or 24 spins for 500x. The base game is capped at 705x the bet, while the stated max exposure is 47,050x. The in-game help also mentions a 200,000x cap on the 24-spin purchase, which suits punters who prefer to skip the grind.

How to Win at Boo Slot

With a 4x4 layout and 256 ways to win, you don’t chase lines. Any symbol combo starting on the leftmost reel and landing on consecutive reels can do the job. Stakes run from 10p to £10, so I set a level that keeps me spinning long enough to reach features. The Play button handles single rounds, while Autoplay can run a batch if allowed in your jurisdiction. I keep session stops handy, as the game can run hot or cold.

There’s a clear split between base and bonus. Reactions and the odd x4 wild can top up the balance, yet most of the heavy lifting comes from sticky position multipliers in free spins. When I’m hunting, I’m happy to grind for pumpkins, but if I’m short on time I’ll price up the Feature Buy. Twelve spins at 90x is relatively tame compared to the 500x option, which needs a deep pocket and a steady head.

Boo Slot RTP & Volatility

Big Time Gaming lists Boo as very high volatility, and it plays that way, with stretches of quiet followed by sudden bursts when multipliers line up. The default RTP sits at 96.54%, though some releases carry a 94% setting, so I check the info panel before spinning. The headline win potential is 47,050x the stake, yet the base game is limited to 705x, which explains why the free spins round and the buy feature attract so much attention.

The Final Verdict on Boo

Boo feels like a neat seasonal reskin of BTG’s 4x4 idea, but the maths holds plenty of bite. The gap between base and bonus is sizeable, so patience pays when those sticky multipliers start to build. I rate it as a tight, ghosty performer that can throw out chunky ladders in free spins, especially across longer runs. If you favour feature buys, the two price points give options, though the 24-spin ticket is an expensive punt best suited to braver bankrolls.
