Horror Hotel slot game from Relax Gaming can be played on a 6 x 6 reels setup and is playable on any mobile device. It offers an RTP of 96.17% with higher volatility. Playing this game, you'll encounter different features and symbols that can help you win including the symbols that can pay between 500 and 5,000 x your stake for 35+ in a cluster, and between 0.1 and 1 x your stake for the minimum of 5 matching symbols in a cluster. In this game, the Wild symbol steps in for pay symbols to help complete or improve cluster wins. The non-winning symbols are removed via the Cascading mechanic. All winning symbols, including wilds, are turned into Mystery symbols, then you'll get a respin as all non-winning symbols are removed, and the mystery symbols drop to the bottom of the grid before the new batch of symbols drops. After the drop, all mystery symbols turn into randomly chosen matching symbols. This process repeats if the original cluster win is improved, or a new winning cluster is created. The Bonus Round triggers from 3 scatters, and this gives you 5 free spins. You get an additional free spin on top of that per additional triggering scatter, and scatters also award +1 extra spin during the feature. You will have an additional wild per spin that follows. The win multiplier increases by +1 per cluster win, and it never resets as long as the feature lasts. You can play this game starting between a minimum of 0.10 to a maximum of 50 per spin.
