Review Overview
Summary
Boo slot is a 4x4 grid-based game with stacked symbols and 256-ways to win. The theme is rather daft looking cartoon ghosts but the halloween background is much more convincing. There's 4 ghosts which pay 3 and 4-of-a-kinds from 2 down to 0.8x and 6 royals which only pay for 4OAKs at 0.4 down to 0.2x. Wilds can land on reels 2 to 4 and will be at 1 to 4x in multiplier, multiplicative so up to 64x is possible. Wins are replaced by tumbles from below and only ghosts or Wilds can appear as replacements. Three or more pumpkins will award 12 free games and a random multiplier of 2-4x will be stuck to the position of 1 to all triggering scatters. Every time a win occurs with either ghosts or Wilds involved, at least one existing position will have its multiplier increased by 1x or a new position will get one added. These are sticky and have no limit to how high they can rise plus they can be on column 1 as well, so it's possible to have 4 multiplicative amounts in one single way of ghosts. Three pumpkins in one spin awards +3 spins and a haunting win of over 20,000x bet is possible here.
