Boo
Boo is a graveyard-set, ghost-themed slot from Big Time Gaming built on a 256-ways pay structure. Rainbow-hued Wild symbols sit on the middle reels and can hold multipliers up to x4 in the base game, while landing three or more pumpkin-shaped Scatters opens a Free Spins round. Across sixteen onscreen spots, individual multipliers persist and climb further when extra Scatters retrigger spins. A Bonus Buy feature also lets players pay directly for entry into the Free Spins round.
