  • Green Cube Symbol: The feature symbol awards Multiplier ranging from x2 to x5 or x10. If more than 1 Green Cube symbol gets activated, the sum of the Multiplier values is considered.

If there is more than 1 red glowing symbol, then the numbers displayed on both are added to compute the total number of Free Spins won. The Free Games Feature can be retriggered up to 100 Free Spins.

During the Free Games, the row of Prize Line symbols appears right below the reels. On each spin, the leftmost symbol and any feature symbol that was activated on the previous spin are removed. A new feature symbol appears on the extreme right and the entire row of symbols shift to the left until all 5 symbol positions are occupied.

During the Free Games, if a Cosmic Heart symbol occurs, it activates the feature indicated by the Prize Line symbol right below the reel on which the Cosmic Heart symbol has landed. For instance, if the Cosmic Heart symbol lands above the Red Glowing symbol, the player wins additional Free Spins equivalent to the number displayed on the feature symbol. Likewise, the Pink Glowing Cube symbol rewards credits valued between 2 and 20, the Blue Wild symbol with down arrow transforms all the symbols on the corresponding reel to Wilds, the Blue Wild symbol with random arrows awards Wilds on random positions (3 to 10 Wilds), and the Green Glowing Cube symbol awards a Multiplier ranging from x2 to x5. 

3.    Wild

The galaxy symbol marked as Wild is the Wild symbol. It can substitute for all the symbols in the game except the Cosmic Heart symbol and the 6 Prize Line feature symbols. The Cosmic Heart symbol also turns into Wild after it lands on the reels and acts as a substitute for all the symbols except the 6 Prize Line feature symbols.

4.    Pick Bonus Feature

Each gem reveals a certain prize amount and the player wins the product of this prize amount and the Multiplier value. After every 7 picks, the Multiplier value increases by x1.
