Boo Demo & Review

Boo Review

Boo slot brings a spooky twist to BTG’s niche 4x4-reel series, arriving just in time for Halloween. While it's pretty much a reskin of Pop, the differences lie in the theme and the adjusted math model. The most noticeable change is the significantly reduced base game max win of only 705x. The fairground setting has been transformed into a foggy, haunted graveyard under the moonlight, complete with eerie carved pumpkin lanterns scattered amongst the tombstones.

The base game revolves around the floating Ghost symbol reaction wins mechanic, where winning symbols vanish to make room for new ones. Multiplier wilds come in handy once in a while, boosting your wins in the reaction sequences. However, the real thrills are unleashed in the bonus round, where upgradable position multipliers take center stage. These multipliers can grow to impressive heights, potentially leading to wins of up to 47,050x your stake. This is a solid offering for a Halloween game, yet its attainability remains uncertain.

Big Time Gaming - Slot Developer

Big Time Gaming has been a powerhouse in the online gaming industry since 2011. Their claim to fame is the revolutionary Megaways engine and the iconic Bonanza Megaways. With a portfolio of 85+ slots, numerous awards under their belt, and multiple licenses, BTG has consistently delivered hit releases, solidifying their position as a leading innovator in the world of online slots.

Slot Theme And Storyline

Big Time Gaming’s Boo slot invites you into a spooky graveyard bathed in the eerie glow of the full moon. Fog swirls around tombstones adorned with grinning jack-o'-lanterns, creating a chilling atmosphere. The reels are filled with floating ghost symbols, and these pop like balloons when part of a win. Overall, Boo is a visually captivating Halloween adventure that promises thrills and chills with every spin.

Boo RTP, Volatility, And Max Win

The top-tier Boo RTP of 96.54 % is a bit above the industry average, which hovers around 95-96 % according to our research.

This is a high volatility installment from Big Time Gaming, and the Boo max win is 47,050x your stake.

Boo Rules And Gameplay

You can play with bets between €0.1 and €10 in Boo slot, which is a pretty narrow bet range compared to most slot games. The game plays out on 4 reels with 4 symbols per reel and 256 win ways. You win when matching symbols appear anywhere on 3+ adjacent reels starting from the leftmost reel towards the right. The Rainbow Ghost serves as the game’s multiplier wild, substituting for pay symbols and boosting wins. Scatters trigger the bonus round.

Boo Bonuses And Special Features

The Reaction mechanic is a bit different than you may be used to in Boo slot, and you’ll also benefit from multiplier wilds and a bonus round. Let’s check it all out!

Reaction Wins

Winning symbols are removed via the Reaction mechanic, and premium Ghost symbols, Ghost Multiplier Wilds, and/or Pumpkin Scatters float up to fill the empty positions. This process repeats indefinitely as long as you keep winning.

Multiplier Wilds

The Ghost Wild lands on reels 2 and 4 only, and this rainbow-colored ghoul comes with possible multiplier values of up to x4 attached. Each wild applies its multiplier if part of the same win, and wilds substitute for any pay symbol to help complete or improve wins.

Boo Free Spins

The Bonus Round triggers from 3+ pumpkin scatters in view in Boo game, awarding 12 free spins. All positions are enhanced with multipliers for the duration of the feature, and Ghost and/or Wild symbol wins upgrade a number of the position multipliers per initial win (not per reaction). At least one position is upgraded by +1, +2, or +3, but this amount increases by +1 each time the position is upgraded. At least one of the triggering positions is upgraded with a starting multiplier of x2, x3, or x4, while the remaining positions start at x1.

The additive position multipliers only affect Ghost and Wild symbols. Landing 3+ scatters in the same reaction sequence awards +3 extra free spins, while also adding +1, +2, or +3 to one of the retriggering positions. Ghost Wild multipliers come in addition to the position multipliers, further boosting your total win.

Review Summary And Verdict

Big Time Gaming's Boo game certainly sets the stage for a spooky adventure with its eerie graveyard setting and floating Ghost symbols. However, it's difficult to overlook that this is essentially a Halloween-themed reskin of their less-than-successful Pop slot. While the base game offers multiplier wild action, the maximum win of 705x pales in comparison to the potential of the bonus round, where the win cap skyrockets to 47,050x your stake.

Even with this massive boost, the FS potential in Boo slot still falls short of its predecessor. Moreover, the original boasts a far more rewarding base game, at least in theory, but BTG has faced criticism for the scarcity of significant wins in their slots. It's unlikely Boo will change that reputation, but its captivating visuals and upgradable position multipliers make it an enjoyable enough option for Halloween enthusiasts seeking a spooky fun gaming experience.
