Playing Cosmic Heart is fairly simple. There is a 1 to 200 coin betting range per line. To view the game's rules and a description of all the features, click the + button in the upper right corner, followed by the I button.
The paytable looks like this:
There are unique Prize Line feature icons above the reels. The Prize Line feature symbols move one step to the left with each spin as the leftmost sign vanishes and a new symbol enters from the right. This top reel can contain any of the six different Prize Line symbols, each of which has a unique function.
You begin the Pick'em bonus game with the same number of lives you received with the Prize Line symbol, a 1x multiplier, and a set of "cosmic slider" reels (s). When you pick the green gemstones that are sliding across the screen, prizes between 1x and 10x will be revealed.
After that, the prizes you receive are subject to a multiplier that rises by one for every seven gemstones you choose. When you run out of lives, the feature terminates. One life is lost when a green gemstone displays a black star rather than a prize won.
The free spins bonus round, which takes place on a different kind of reel set, is the last one. When you use up all of your spins or when a maximum of 100 spins have been played, the feature comes to an end.
