All about the Gem Strike Online Slot

Diamonds are not only a girls best friend, we here at Thunderbolt Casino also love all that is glitter and gold.

Gem strike has arrived and it's made quite the splash. It has a gameboard that will make you think you're dancing on a rainbow, a soundtrack that will make you feel like you're having Breakfast at Tiffany’s and multiple features that will have you skipping to the bank.

This new slot has an outstanding bonus round and a unique cascading reels feature that is active during the base game. The cascading reels feature works by replacing winning symbols with new ones (a.k.a cascading wins). This continues until no extra winning combinations occur. What's even more exciting is that a prize multiplier builds up over successive wins resulting in x1 prizes for the first cascading symbols through to x3 for the third cascading symbol or better. Additionally, the scatter symbols will not be replaced nor tumbled, even when they trigger free games.

This slot is bursting with so many different ways to win! We suggest you keep reading so that you can take advantage of our fantastic offer (that's right, we're talking free spins).



As the #1 Gemologist at Thunderbolt Casino, you'll have to seek the paytable where you'll find rare crystals, precious gems, valuable stones, and other low and high-paying symbols.

But if you're looking for the real treasure (you know, the kind that would make Jack Sparrow drop his rum), then we'll let you in on a little secret. We've found something that shines brighter than a diamond. We're referring to the lightning scatter and the multicoloured wild symbol that substitutes all symbols except the scatter symbol to complete winning combinations.


Bonus Rounds

Are you entering the Cave of Wonders or the Gem Strike Bonus Round? All we know is that it's one of the most uncomplicated yet rewarding bonus rounds we've ever seen. Simply get your hands on a lightning bolt and you'll be rolling in Free Games.


Free Games

When 3 or more scatter symbols appear anywhere on the gameboard, then the Free Games feature is triggered:

  • 3 Scatter Symbols trigger 15 Free Games.

  • 4 Scatter Symbols trigger 30 Free Games.

  • 5 Scatter Symbols trigger 50 Free Games.

The tumbling continues after each win, until no winning combinations occur.

If the chance to receive 50 Free Games is not quite enticing enough for you, well this slot machine also features a Prize Multiplier Indicator. This effective addition will be displayed on the gameboard, and indicates the multiplier that will apply to your next win. This builds up after each successive win from your original free games spin. The Prize Multiplier is also carried over from the base game but goes from x1 on the first tumble to a maximum of x5 on the fifth consecutive tumble.

So if luck is on your side (come on, you're playing at one of the best online casinos, you know it will be) and you happen to get a few big wins in a row, then you could receive some generous and dazzling payouts.

Keep in mind that the Free Games are played at the bet of the triggering spin and the bet cannot be changed. The Free Games will end once there are no more Free Games remaining or when the maximum payout is achieved. After you have completed all of your Free Games then a banner will display your total winnings achieved during this feature.
