Features & bonus round
- 3x3 grid with 5 win lines, four jackpots (Mini, Minor, Major and Grand) and a max win of 3,000x the stake
- Thunder Diamond Feature: a Thunder Bonus symbol together with any Bonus symbol collects the values of all Bonus symbols, including the jackpot symbols, and adds them to the win
- Bonus Game: a Bonus symbol on every reel triggers it; only Bonus and Thunder Bonus symbols land, you start with 3 re-spins and every new symbol resets the count to 3
- In the Bonus Game, Thunder Bonus symbols land on reel 2, stick in place and collect multipliers of x1, x2, x3, x5, x7, x10 or x15
- Pile of Thunder Diamonds Feature: any Bonus symbol in the main game can trigger it and add enough Bonus and Thunder Bonus symbols to start the Bonus Game
Thunder Diamonds suits players who like compact classic-style slots with a respin bonus and jackpots to chase. Try the free demo first to see how often the Bonus Game triggers, and set a budget before playing for real money.
