Gemstone Jackpot

Gemstone Jackpot

Do your eyes widen at the sight of sparkling diamonds? Then hold on - these gems will make you weak in the knees! Open our treasure chest and land the jewels in the correct order along the 10 win lines - and you've got a winning combination, which triggers the ‘Lock & Spin’ feature with which you can really cash in!

Your aim is to land 5 identical symbols along a win line. Winning combinations start on the first reel on the left and run along an active win line to the last reel on the right in the regular game. To win, the symbols must lie next to each other without any other symbols coming between them.


Select the amount of credit you would like to take with you to the game upon entering Gemstone Jackpot. You must then select your bet per line and number of lines that you would like to play with by using the respective ‘+ / -’ symbols. You can spin the reels once by clicking on the 'Start' button. Click the 'Autostart' button to trigger automatic spins and click the ‘Stop' button to stop automatic spins.

Click on the 'Paytable' button to go to the winnings overview. Here you can view the potential winnings awarded for each winning combination based on the size of your current bet.


It's double or nothing: The "Gamble" button will appear as soon as you have a winning combination (see Paytable). You can double your winnings with the Gamble-Game. Your winning odds are 50:50. If you would like to gamble, simply click on the 'Gamble' button to start the 'Gamble' game. If you do not want to gamble, just press the 'Collect' button.

'Lock & Spin' Feature

After each win, the compass rotates and the reels move up one position in the direction the compass indicates. If this leads to a further win, the reels keep moving step by step in the same direction until no new win is achieved.

Poseidon bonus

Land a winning combination on one or more lines to trigger the ‘Lock & Spin’-Feature. All symbols in your current winning combination(s) are locked to the reels and all other positions are spun again. Any new symbols which compliment your fixed winning symbols also become fixed and all other positions are spun again. You will continue to receive spins as long as you keep landing complimenting symbols. As soon as the feature comes to an end, you will be credited with your winnings and all locked symbols will be released.

The theoretical return to player for this game is 95.08%.
