About this Slot
Bastion is a fantasy medieval slot from Voronoi with an RTP of 96.7%, high volatility and a maximum win of 30,000x. The game plays across six reels and five rows using cluster pays mechanics.
Matching eight or more symbols anywhere on the grid triggers cascading reels. Winning symbols are removed and remaining symbols drop downward as new symbols fall from above. Cascades continue until no more winning clusters form.
Golden harps act as scatter symbols. Three harps award 10 free spins, four harps award 12 free spins, and five or more harps award 15 free spins. These triggers occur after the final cascade ends.
Gunpowder barrels explode after each winning tumble concludes. Barrels clear nearby symbols and combine multipliers from those removed symbols. Empty barrels also explode but do not add any multiplier value. The accumulated multiplier bank carries forward into the free spins round.
Harps that remain on the grid when free spins end retrigger additional spins.
Four selectable bonus modes are available before play begins. Each mode alters the conditions affecting harps, barrels and free spins play.
