5 Best Horror Slots to Play Online

1 – Under the Bed  

Under the Bed is one of the best Halloween-themed slots, so naturally it has to make my list of top horror slot games as well. It is the perfect showcase for BetSoft and its famous 3D graphics. Plus, with a high RTP of 96.40% and a hit rate of 44.96%, there’s every reason you should play it. 

Things certainly go bump in the night in Under the Bed. A range of ghosts and ghouls keep the children up at night during gameplay. It’s your job to trigger the bonuses and keep the beasts at bay. 

The slot features free spins, persistent wilds, and a spooky second screen bonus. Utilizing 3D graphics to the max, you must hunt out monsters to unlock cash prizes. 

SlotsandCasino is our go-to online casino for Under the Bed and 100s of other slots. You can claim a 300% sign-up bonus when you open an account and make your first deposit. 

2 – Cursed Crypt

Brave the cursed reels and gun for a 10,000x max payout in Cursed Crypt from Hacksaw Gaming. While Hacksaw’s game doesn’t boast the 3D graphics of BetSoft’s titles, there’s plenty of atmosphere, particularly in the moody soundtrack. 

The Curse symbol may land anywhere, spreading upwards to create ‘cursed’ positions. These are replaced with random symbols. You can trigger free spins in Cursed Crypt by landing 3 or 4 scatters on the reels in any position. 

It’s not just the eerie music that makes Cursed Crypt one of the best horror slot machines. The 96.22% RTP ensures long-term gains too. 

Why not give Cursed Crypt a play at TrustDice? It’s one of our top-rated cryptocurrency casinos for horror slots players. You can even bag yourself an enormous crypto deposit match when you sign up. 

3 – Zombie World

There are a variety of amazing horror slots at Bovada Casino, but Zombie World is our pick of the lot. The evil dead have taken over the world, but it’s your job to hunt the graveyard for hidden treasures. 

The slot features free spins, during which giant scatters may fall to retrigger additional spins. Look out for blazing reels, too, during the free spins bonus. Reels combine to create giant 3×3 symbols which count as nine symbols in one. 

In addition, you can trigger one of three fixed jackpots by filling all reel positions during the Pot Bonus. You bag the Mega Jackpot by filling every reel spot with the correct symbol. 

Bovada Casino regularly tops our go-to list for games and horror slot machines. For an all-round gambling experience, Bovada is hard to beat. Plus, you can claim one of the biggest crypto bonuses in town when you sign up.

4 – Blood Eternal

You may remember BetSoft’s Blood Eternal making it into our list of the best vampire slots. The vampire-themed game also makes a justified appearance here due to its high hit rate and large jackpot. 

You play Blood Eternal on a 5×3 reel set-up where vampires go on the hunt for human victims. The vampire and human may appear on adjacent reels side by side. When this happens, you trigger free spins. 

Look out, too, for the bat symbols. These can appear as single or double bats and may occupy the same space. 12 bat symbols can appear on a single line for a top payout worth 50,000x. 

Looking for a great casino to try out Blood Eternal? Read our DuckyLuck Casino review and give the game a try. The casino boasts dozens of top 3D slots from BetSoft. Plus, you can kickstart your slots journey with a huge 500% sign-up bonus. 

5 – Shell Shock

Rival Gaming’s Shell Shock was released in mid-2024 at some of the best online casinos, including Wild Casino. It’s easy to see why this has been earmarked as one of our top horror-themed slots. 

Shell Shock takes place in Dr. Frankenstein’s laboratory where radioactive potions sit alongside jarred brains and other delights. Game logos act like wilds and apply a 2x multiplier to any combination they complete. Plus, you can trigger 10 free spins by hitting 3–5 scatters. 

The average RTP of 93.95% may not sound like the best return. However, the beauty of Shell Shock is the low volatility that can make a change from the hit-and-miss nature of some BetSoft slots. Why not try Shell Shock for free at Wild Casino? You can play before making a deposit and claiming matched bonus funds.
