Introduction to Opa Santorini!
Opa Santorini! is a casino slot from NowNow Gaming that welcomes you to the sun-soaked Greek island of Santorini. The island’s iconic white-washed houses, blue-domed churches, and famous sunsets attract over 3 million tourists every year. The Greek Mythology theme is one of the most used in the industry, so it’s nice to visit modern Greek for a change, offering sharp visuals and a lovely Greek soundtrack. In terms of gameplay, it revolves around the Windmill Feature, which transforms winning symbol positions into multiplier values, similar to what we’ve seen in the popular “Le” series from Hacksaw Gaming, featuring games like Le Fisherman.

Special Features & Slot Mechanics

What features are available in the slot of Opa Santorini!?
The features of this slot game are Avalanche, Wild Symbol, Windmill Feature, Zeibekiko Bonus (Bonus Game), and Feature Buy.

Avalanche
The Avalanche feature is activated when a win is created, and the winning symbols will be removed from the reels. New symbols will fall from above and allow new winning combinations; this will continue as long as new winning combinations are created.
Whenever a winning combination is created, the winning symbols get highlighted.
Wild Symbol
The Wild Symbol substitutes all symbols except the Scatter and Wildmill Symbols and helps you create winning combinations. Creating a win with 5 Wild Symbols pays 20X the bet.
Windmill Feature
This feature can be triggered whenever a Windmill Symbol appears on the reels on the initial spin with highlighted winning positions. The Windmill Feature is triggered when the spin is complete and transforms all winning highlighted positions into other Windmill Symbols with a multiplier value of 1X, 2X, 3X, 4X, 5X, 10X, 20X, 50X, or 100X. All multipliers are summed up and applied to the initial winning combination.
However, it can also transform into a Shutter Symbol (blue door), revealing one of the following boosters:
Add = Reveals a multiplier value which is added to all Windmill Multipliers in view and previously opened Shutter Symbols.
Collect = Collects all Windmill Multipliers and opened Shutter Symbols in view, and adds the total to its own multiplier while all collected values remain unchanged.
Add + Collect = Starts with adding its value to all existing multipliers in view, then collects the updated values from all Windmull Multipliers and opened Shutter Symbols, and adds the total value to its own multiplier.
Collect + Add = Starts with collecting the value of all current multipliers and adds the total value to its own multiplier. It then adds its value to all existing multipliers in view.
The Shutter Symbol can have the same multiplier as the Windmill Multiplier: 1X, 2X, 3X, 4X, 5X, 10X, 20X, 50X, or 100X.
Zeibekiko Bonus (Bonus Game)
This feature can be triggered by landing 3 Scatter Symbols on reels 1, 3, and 5 during the Base Game, awarding 10 Free Spins. Landing 2 or 3 Scatter Symbols during the feature will grant +2 or +4 additional Free Spins, respectively.
Here, you play the Bonus Game with the same Base Game mechanics, but with one boosting effect. On every Free Spin, all winning symbols are highlighted, even if no Windmill Symbol appears. The highlighted positions remain on the reels and carry over to the following Free Spin as long as a win is created.
When a Windmill Symbol lands while at least one highlighted position is present, the Windmill Feature is triggered. When the feature is reset, and payouts are complete, the game grid resets.
Feature Buy
If you want to take advantage of the Bonus Game immediately, you can use the feature buy options:
2X (Bonushunt Featurespins) = Each spin is 3 times more likely to trigger a Bonus Game. Played with high volatility and an RTP of 96.26%.
50X (Windmill Featurespins) = Each spin guarantees at least one Blazing Wild. Played with high volatility and an RTP of 96.29%.
100X (Zeibekiko Bonus) = Activates the Bonus Game. Played with high volatility and an RTP of 96.31%.
Final Thoughts on Opa Santorini!
NowNow Gaming invites us to the popular Greek island of Santorini, offering a wonderful backdrop filled with the signature white-washed houses and blue-domed churches. A charismatic Greek guy dances while enjoying the captivating traditional Greek soundtrack, making this a well-produced homage to one of the Mediterranean’s most popular islands.
Looking at the gameplay, it revolves around the Windmill Feature, which works as a revealing mechanic, similar to what we’ve seen in games like Le Cowboy and Le Bandit. Whenever a winning combination occurs, all winning symbol positions get highlighted. If a Windmill Symbol appears in view with highlighted positions, they’re transformed into a multiplier value ranging from 1X to 100X, creating good win potential. We also get the help of the Shutter Symbol, offering boosters that increase the multiplier values and create an engaging experience in both the Base and Bonus Game. However, whenever the Windmill Feature isn’t triggered, the Base Game feels basic and would need additional features to elevate the experience.
The Zeibekiko Bonus is the game’s main selling point, offering sticky highlighted positions. Unfortunately, they reset after a Windmill Feature trigger, which feels like starting over, missing out on some massive win potential. Overall, we truly enjoyed the Greek vibe of this game, creating an immersive slot experience. In terms of gameplay, there’s a clear connection to the ”Le” series revealing mechanics, but with a lighter, straightforward approach, it offers an effective formula that can lead to solid payouts.
Opa Santorini! is a slot that transports you to the lovely island of Santorini for an immersive environment and a Windmill Feature that reveals multipliers up to 100X.
