Halloween will soon be upon us, and Booming Games is preparing a very special slot machine for it, called Horror House. With some of the scariest creatures around present on its reels, the game also relies on excellent features and an expanding game area, to bring you big wins. All this, at the cost of playing a slot with high volatility though, something that you’d expect, but which you might not be happy about.

Horror House gives us 5 reels initially, but with only 45 ways to win active, thanks to its 1-3-5-3-1 setup. Form wins, and you end up with up to 3125 ways to win during the following re-spins, and eventually you could even play 8 free spins with the full game area unlocked. In a game with high volatility and a 96.04% RTP, there is the potential to win up to 4,800x the stake.

Betting and Prizes

The bet button, with its stacked coins, is the way to get a new screen, where all wager values are listed. Simply click on the appropriate one, to change the amount which will go into the next round. The smallest value is $0.10, while the biggest is $100.

A top jackpot of 4,800x the stake is a pretty good return for a slot machine, though for a game with high volatility we’ve seen plenty do even better. You do get wins fairly often, the odds being that a combo will form in 28.42% of the spins you get through, but you still risk quite a bit with this one.

They’ve announced the Return to Player for the game as well, and it’s calculated to be 96.04%, so it’s considered a fair option.

Horror House Slot Features

If we look at the game’s features, there are several present, including the wild and a re-spin with reel expansions, leading to free spins.

Wild Bat icons are going to be present in the game, and you’re going to use them in any new combinations formed on their reels. Acting as a substitute is quite a bit easier, if the slot machine has ways to win, rather than paylines. These wilds are only available on the last four reels.

Forming a win might prove to be difficult at times, even with that 28% hit frequency, because of the 1st reel offering only 1 symbol initially. However, once you get the ball rolling, re-spins will follow, during which you unlock 2 new positions on the reels. This boosts the number of ways to win, and gives you additional chances at more wins. If that happens, there is an additional re-spin triggered, with even more positions unlocked.

Eventually, after 6 winning spins, you can end up with the full 3125 ways to win on 5x5 reels, and then the free spins trigger. You get 8 free games there, with all ways to win unlocked.

Theme & Design

Given the nature of a slot like Horror House, it’s to be expected that it will feature the usual creatures that have given us nightmares while we were young. Dracula is a big one, as is Frankenstein’s monster, or a Werewolf, Black Cats, Black Widow Spiders and the Chucky Doll. The Royals are green and covered with cobwebs. The Bat Wild is the only feature symbol involved.

The entire set of reels is placed against the Horror House, which the title mentions. It’s a neglected building, with windows which are boarded up, surrounded by trees with no leaves, so it all looks quite depressing. A perfect experience then, for a slot machine to play on Halloween.


I couldn’t find a lot of things that are wrong with Horror House slot. The game can pay very well, it’s got the right odds in the long run, and it incorporates mechanics that keep you on your toes and having fun. The expanding reels have a way of doing that, especially as you can do it whenever a winning combo forms.
