The ghosts are creeping out of the graveyard tonight and the bats are hanging out in the belfry. But there’s nothing to fear. They are your undead guides to fun wins and great bonus games. BOO™ is a 5-reel, 5-line game brought to you by Kodiak Gaming. This game is multi-denominational (5cent, 10cent, quarter, half dollar, $1, $2, $5 and $10). A multi-win free spin bonus pays more with more (3, 4 or 5) bonus cattle. On the primary bonus game, they can ride through and pick the points on their winning tombstone in the Tombstone Bonus.
