About the game

The symbols of this free slot machine welcome bonus game feature four different bright coloured crystal molecules. The green football shaped crystal, the blue shard shaped crystals, pink cube crystals and purple ones in artistic shape. The top one is the green that pays a thousand times on your betting when five of a kind show up on reels. Watch out for the paylines where you can win. The low paying ones are the elements such as au, pt, h2o and o2 from which you can win the stakes between 30x and 60x on five of a kind. The game logo and the X mark are the additional symbols from which you can win bonuses.

• The lab spins: When the game logo lands on the cortex, that is on the second row of the second reel, you are given ten free spins. What also happens is the symbols on first three reels shifts to the last three and remain sticky until free games end.
• Scatter X: The X mark is the scatter feature here and every appearance of this symbol in a winning combination doubles your wins. More Xs will further multiply your wins and that can be massive sometimes.
