Horror Hotel Slot by Relax Gaming

Every win in this haunted hotel sets off a re-spin chain. Land any cluster of five or more matching symbols on the 6x6 grid and the entire winning cluster converts into Mystery icons, every non-winning symbol gets vaporised, and a fresh drop fills the empty space. The Mystery icons then reveal as one matching symbol type, paying again if they extend the original cluster or join a new one that forms from the dropped symbols. The chain only ends when the next drop produces no new win, or when wins are coming solely from the Mystery reveal itself.

Clusters need at least 5 connected symbols to pay, and the payout tiers jump in chunky bands - 5/6/7/8/9, then 10-11, 12-14, 15-19, 20-24, 25-29, 30-34, and the full 35-36 carpet. The H1 ghost girl pays 5,000x for a 35-36 cluster, the mid trio (vampire, witch, Frankenstein-style figure) tops out at 1,500x, and the three coloured potion lows max at 500x. Wilds (WR) substitute for everything except the skull-shaped Bonus scatter.

Three or more Bonus symbols land you in Free Spins with 5 spins to start, +1 spin per extra Bonus on the trigger, +1 again for each new Bonus during the round. The bonus stacks three modifiers on top of the base game's cluster mechanic: a guaranteed Wild count that climbs each spin (1 Wild on spin one, 2 on spin two, 3 on spin three, and so on), the Mystery re-spin chain still firing on every cluster, and a progressive win multiplier that ticks up before each Mystery conversion resolves. The whole feature is hard-capped at 20,000x your bet - hit the cap mid-round and the rest of the spins simply pay nothing.

The Buy option sits at 100x stake and guarantees 3+ Bonus symbols dropping straight into Free Spins. Single-tier purchase, no cheaper or premium variants like some Relax catalogue mates.

Visually this leans Tim Burton rather than slasher. A moonlit gothic mansion sits behind the reels, twisted bare trees curl from the left, a derelict castle silhouette rises on the right, and tombstones scatter the foreground. Premium symbols glow cyan, the lows are jewel-coloured potion bottles in purple, green and red, and warm orange light spills from cracks in the hotel doors. With a hit rate around 16%, dry stretches are normal - the design banks on big Mystery cascades when wins do connect.
