About this Slot
BIOREELS is a sci-fi themed slot by Reactor Games with an RTP of 96%, high volatility and a maximum win of 25,000x. The game uses a 5x5 reel layout with Cluster Pays, where five or more matching symbols connected horizontally or vertically form a win.
Cascading reels remove winning symbols and drop new ones into their place. Multiplier Canisters land on the reels displaying values between 2x and 500x. Rare Canisters show values of 1,000x, 2,500x, 5,000x, 10,000x or 25,000x. After each cascade ends, all canister values on screen add together into a total multiplier.
Three Bonus symbols trigger the Bonus round with 10 free spins. Four Bonus symbols trigger the Super Bonus with 10 free spins, which starts with a 2x total multiplier. Five Bonus symbols trigger the Epic Bonus with 10 free spins, which starts with a 5x total multiplier. During free spins, canister values accumulate into the multiplier, which never decreases. Every winning spin uses the accumulated total multiplier. Landing additional Bonus symbols during free spins awards 1 extra spin each.
Bonus Symbols can trigger bonus rounds through standard play or via purchase. The Bonus buy option costs 100x bet. The Special buy option costs 250x per spin. The Super Bonus buy option costs 300x bet. The Mystery Bonus buy option costs 500x per spin and can trigger the Epic Bonus. Hunt and Super Hunt buy options cost 3x and 6x per spin respectively.
