About this Slot
System Error combines crime and sci-fi themes with an RTP of 96%, medium volatility and a maximum win of 5,000x. The game features cascading reels that create chain reactions when winning symbols land, while wilds, scatters and multipliers drive the action. Scatter Pays awards payouts on scatter placement alone, and multiplier symbols boost wins on the spin they land.
Three bonus buy options accelerate play. Bonus Hunt costs 2x bet and increases the chance of free spin scatters by 3x. Overclock costs 50x bet, guarantees three multiplier symbols per spin and allows them to persist through wins, though free spin scatters are blocked during this mode. System Breach and Total Meltdown each award 10 free spins at costs of 100x and 200x bet respectively. During System Breach, multiplier symbols accumulate per spin but reset after each one. Total Meltdown differs by letting multiplier symbols accumulate across the entire bonus round without resetting between spins.
