About this Slot
Bumbo is a space-themed slot from Slothgames with an RTP of 96.7%, high volatility and a maximum win of 50,000x. It plays across 5 reels and 5 rows with cluster pays, awarding wins when matching symbols touch horizontally or vertically.
Wild symbols form 2×2 matching groups that bank above the board as Wild Boosters. When the next wild lands, it uses a banked Booster to spread across the board; in the base game, the bank is then spent.
Job activates anywhere on the board and marks cleared cells during the cascading tumble. Once the tumble ends, marked cells convert into treasure or multipliers. Super Job converts all 30 cells on the board regardless of whether wins have landed.
Three full bars trigger 8 free games. Banked Wild Boosters carry into the bonus round and are never spent there. During free spins, the tumble multiplier starts at 2x and increases with every drop.
Lucky Wheel is a single-spin feature that can award the game's top prize of 50,000x.
