Developer Horror Hotel is a Relax Gaming video slot built around a cluster payout mechanic on six reels, with high volatility and stakes from €0.10 to €50. The game is set in an old graveyard and hotel-themed horror environment, where winning symbols group together rather than form traditional paylines. Its RTP is listed at 96.17%.
The slot includes a Mystery feature that converts all winning symbols into Mystery symbols and adds one re-spin. Players can also trigger free spins by landing three or more bonus symbols. During the bonus round, each bonus symbol adds wilds, with the number of wilds increasing by one on each consecutive free spin.
This page provides the Horror Hotel demo version, allowing players to play for free and practice before playing for real money. The maximum potential payout is 20,000x the bet, making the game of interest to players who follow high-volatility cluster slots with bonus rounds and expanding wild features.
