Introducing Horror House, Booming Games’ latest release

Halloween is fast approaching and with everyone preparing for the trick or treat holiday, Booming Games have done exactly the same, preparing a special slot called Horror House. With some of the scariest creatures we know of that only appear during All Hallows’ Eve littering the reels, the game has an impressive graphical detailing as well as some stunning features and expanding play area. These help the player bring in impressive wins. All this comes at a cost unfortunately, and that cost is a slot with high volatility, something we all would expect. Horror House gives 5 reels initially, with only 45 active ways to win; this is thank to the 1-3-5-3-1 set up that is at play here. This can be expanded during the features and will increase to 3,125 ways to win when you unlock the entire area.

Betting and RTP for Horror House

Betting begins at $0.10 and increases up to a maximum of $100 per spin, which is perfect to allow all players the chance to get in on the horror action in this brilliant slot. With this range in mind, there is a top jackpot available of 4,800 times the stake which is an impressive return for a small slot.
Wins do occur relatively often, with the odds of forming a combination almost every third spin – the percentage is 28.42%. While this doesn’t sound risky, it could be, you would have to decide for yourself whether the risk was worth the reward.
The RTP (Return to Player) for the game is calculated to sit at approximately 96.04%, so it is considered a fair option for the player. It sits at average for this type of slot on the market.

Symbols and theme of the slot

Since Horror House is a Halloween horror slot, we can expect to see horror symbols and spooky icons littering the reels. Booming Games did not disappoint, filling the slot with the creatures which have given us nightmares since we were small.
The main one is Dracula with his impressive fangs, followed by Frankenstein’s monster with his famous green-ish skin and metal charging rods. Following on we have the hairy and full moon changing Werewolf. These are accompanied by Black Cats, Black Widow Spiders, and the infamous Chucky Doll, wielding his knife as always.
The Royals – A, K, Q, J, and 10 – are shown in green, covered in sticky spider cobwebs. These pay 1x for 5 on a line.
Finally the Bat Wild is the only feature symbol that the player can use. This acts as a substitute for other regular symbols. The only downsides are that it does not have its own value and therefore cannot create its own wins, and can also only land on reels 2, 3, 4 or 5.
The reel set is placed on the front of a Haunted Horror House, as the title would suggest. It is a neglected derelict building with windows boarded up, trees bare to the elements. The whole scene is rather depressing in a ghoulish kind of way. This creates the perfect atmosphere for the horror slot to play out this Halloween.


If we look now to the features of the slot, there are several that jump out, including the respin with reel expansions, wilds, and free spins.

Wild Bat icons are present throughout the slot and can be used to form additional combinations on the reels. Acting as a substitute is easier due to the use of ways to win rather than pay lines.
Forming wins may be a little difficult sometimes, even with the hit frequency of 28% because the initial base game will only have 1 symbol on the 1st reel. One you begin to get respins, 2 new positions will unlock on the reels. This boosts the number of ways that you can win. If you win again, even more positions are unlocked with the addition of more respins. Eventually, once you have had 6 winning spins in a row, you will end up with the maximum 3,125 ways to win with the full grid of 5x5. This will then unlock the free spins which will trigger, giving the player 8 free spins. Unfortunately no retriggers are possible with this free spins feature, however that doesn’t detract from the impressive nature of this slot. To explain the respins a little better, here’s the formations you’ll be looking for.

Respin 1 gives the player a formation of 3-3-5-3-1 with 135 ways to play. Respin 2 has a grid formation of 3-3-5-3-3 with 405 ways to play. Respin 3 gives a grid of 3-5-5-3-3 with 675 ways to play. Respin 4 shows an almost complete grid of 3-5-5-5-3 with 1,125 ways to play. Respin 5 offers the full grid for the player: 5-5-5-5-5 grid with 3,125 ways to play.


Horror House is a great slot to pick up for the October Halloween celebrations. While it gives the player a spooky atmosphere to enjoy as they spin the reels, it also gives the slot industry a unique gameplay regardless of the fact there are not hundreds of features.

The increasing and decreasing game area make for a fun feature for the player, making the respins the main point of this slot that entice the player in. With the prospect of 4,800 times the stake up for grabs, it is definitely worth a play by any player who dares to spin. Remember the high volatility, remember the spook factor, and get ready for a bone-chilling ride as you spin the reels to win the maximum win of $480,000 to be had.
