This spooky slot has been released just in time for the Halloween season, making it a great horror-themed slot. The studio behind Boo is Big Time Gaming, which is a great and well-respected software provider.
Simple in name but fun in nature, Boo is poised to become one of the biggest slot games this Halloween. It's easy to understand and it stays entertaining, even after spinning the reels a few times!
Boo slot overview
Boo is as charismatic as it is adorable - we mean scary! It’s difficult not to fall in love with the little ghosts which populate these slot reels. The artwork has a nice, soft glow to it, which makes for a nice change from some of the older slots and although the background has animated fog rolling around in the background, it’s not too distracting at all.
Rather than having different symbols, Boo instead has different ghosts. Although this can be a little daunting if you’re colorblind, like I am, they also come with distinctive enough features that you can tell them apart quickly across the reels. The standard symbols will be your Ace, King, Queen, Jack, 10 and 9.
If the Boo in the name didn’t surprise you enough, then get ready for the gameplay features and mechanics! These will include Scatters, Wilds, Free Spins, Multipliers and more - which we’ll cover in detail later on in the guide.

Who made Boo?
The Boo slot comes from Big Time Gaming (BTG), a reputable and large company in the industry. You might recognise the name from the Megaways mechanic, which is licensed to BTG, but that isn’t all that this provider is known for. In fact, they’ve also released the Danger High Voltage II, Panda Money, Bonanza Falls, Trigger Happy and Sanctuary slots.
Big Tim Gaming launched in 2011, led by a team of industry experts who wanted to create something different - which is exactly what they did! The Megaways mechanic launched in 2016 and introduced 117,649 ways to win. It went on to become both an industry and a fan favourite.
If you’d like to play Boo, or any other BTG slot, then luckily these are licensed and available in the US through BetRivers, a brand from Rush Street Interactive.

Boo slot features
Boo may look simple, but it has a few tricks up its ghostly sleeve. This ensures that the gameplay feels fresh and exciting as you continue spinning those reels.
Reactions: Every time you get a winning combination, the ghosts will burst and get vanquished from the board. Rather than your typical cascading reels though, these will get replaced with high-value symbols. These will be Free Spins, Wild or Ghost symbols.
Wilds: The rainbow-colored Wilds ghosts are a substitute for everything except the Free Spins symbol and will appear on the second and fourth reels. These Wilds can also come with multipliers, so they can lead to some potentially big combinations!
The final feature at Boo are the free spins…
Does Boo offer free spins?
If you manage to land at least three of the Golden Pumpkin symbols on the reels, then you’ll activate the free spins mode. These don’t differ from the main game too much, so there’s no complicated new rules or anything to learn.
During the Boo free spins, there will be sticky multipliers on the reels, which will chain, even as ghosts pop and reappear on the screens. This means that if the ghosts line up nicely on the reels alongside the multipliers, you can stack wins on top of one another.
If you don’t want to wait for those pumpkins to land on the reels, then you can always use the Buy Bonus feature. Using a $1 stake, 12 free spins will cost $90 and 24 free spins will cost $500.
Boo slot conclusion
The Boo slot from Big Time Gaming is simple in design, but very fun in practice! There’s something very charming and nostalgic about the ghosts which haunt these reels, especially with each of them having a slightly different design from one another. The gameplay loop feels fresh, thanks to the Ghost symbols bursting and being replaced with new ones each time there’s a winning combination.
Overall, this is a great Halloween slot!
