About this Slot
PumpOween features a Halloween, Horror and Fantasy theme, with an RTP of 96.35%, high volatility and a maximum win of 67,666x. The game runs across a 5-by-5 grid using Cluster Pays.
Winning clusters trigger Cascading Reels, with clusters falling to fill empty spaces. Pumpkin Wilds merge into larger squares as clusters cascade. A huge Wild block falls through the cascades, carrying multipliers that increase its value. Bottles on the board double Wild values when landed.
Symbol Removal clears winning clusters from the grid. Special Tiles sit underneath cells and activate after cascades complete on winning clusters. These tiles fire in sequence: Destroy removes symbols, Wild adds Wild symbols, a progress bar tile advances towards a Wild generation event, and Coin awards currency.
Winning cluster cells each count as one progress bar hit. Huge Wild cells count separately for progress bar hits. The progress bar fills at 45 hits to trigger a Bonus, 35 hits to trigger a Super, or 25 hits to trigger an Epic bonus round. When full, the progress bar places between 4 and 15 Wilds on the grid.
During bonus rounds, Free Spins are awarded at 10 spins per trigger. Three Scatters trigger the Bonus feature, four trigger Super, and five trigger Epic. Scatters landing during the feature award an additional 1, 2 or 3 Free Spins.
Players can buy direct access to bonus features. Bonus Hunt costs 3x bet, Regular Bonus costs 150x bet, Tricky Spin costs 300x bet, Super Bonus costs 300x bet, Trick or Treat costs 500x bet, and Chest Pump costs 1,100x bet.
