The Thunderer comes to us from Wizard Games, finished with a clean, modern look. It runs on 20 paylines across 5 reels with a high-variance maths model, and a published RTP of 95.96%.
Where The Thunderer earns its keep is the feature set. A progressive jackpot adds a wildcard payout that can land at any time. Look out for scatter symbols that unlock free spins and extra bonus rounds. With high variance, this one is aimed at players who can ride out the swings for the top wins. On balance, The Thunderer is a dependable option worth a few spins in the demo first.
At 95.96%, the RTP is slightly below the industry average of ~96%. While this is typical for many popular slots, players should be aware of the slightly lower theoretical return.
High volatility means longer gaps between wins, but when wins do land, they can be significantly larger. A bigger bankroll and patience are recommended for this type of slot.
About 1 in 3 spins results in a win. This is a moderate hit frequency that balances win frequency with payout size.
The Thunderer features scatter symbols that can trigger free spins rounds. Landing the required number of scatter symbols anywhere on the reels activates the free spins feature, giving you extra chances to win without additional bets. During free spins, special modifiers may apply to boost your winning potential.
The Thunderer features a progressive jackpot that grows with every spin placed by players across the network. The jackpot can be triggered randomly or through a special bonus feature, offering the chance to win a life-changing sum. The jackpot continues to grow until one lucky player hits the winning combination.
