A super volatile and very mysterious slot. The definition of an unpredictable game.
The main story of the game is a random bottle that throws wilds and multipliers into the board. U never what to expect from it. But it’s nice to have an enhancer that can possibly lead to you to something huge. U can play and win BIG even w/o free spins. Freebies, well, there 2 different modes that can be triggered by different scatters. They are just huge due to progressive multiplier...

Castle of Terror has that vampire themed vibe and these BTG's old school graphics fit in perfectly. The potential that exceeds 90000x is incredible and the slot has a decent feature, that activates the grid and turns premium symbols into wilds, while increasing the overall multiplier. The feature is not always active when it comes to the base game, making a base game a little bit tough, however, in FS it's always active. FS re-trigger once you collect all the drops of blood. Multipliers remain
