About this Slot
Opa Santorini! is a Greek Mythology-themed slot from NowNow Gaming with an RTP of 96.31%, medium volatility and a maximum win of 10,000x. The game uses 5 reels across 14 paylines.
Cascading reels are active during base play, with reel modifiers applying to the symbols that land. A multiplier increases payouts on winning combinations.
The Windmill feature triggers when a Windmill symbol lands alongside existing marked positions. When active, the Windmill reveals special symbols that contain modifiers. Shutter symbols appear only during this feature, and opening each shutter displays an Add, Collect or Collect + Add value that interacts with both windmill and shutter multipliers.
The Zeibekiko Bonus is triggered by landing 3 F scatter symbols and awards 10 free spins. During the bonus, winning positions remain marked across all spins. Landing 2 additional scatter symbols during the bonus awards 2 extra spins, while 3 additional scatters award 4 extra spins. Marked positions continue to award payouts even when the Windmill symbol is not present.
Three bonus buy options are available. Bonushunt FeatureSpins™ costs 2x bet. Activate Windmill FeatureSpins™ costs 50x bet. Activate Zeibekiko Bonus costs 100x bet.
