Instructions:
Match green elements to create a yellow element.
Match yellow elements to create a red one.
Match red elements to create a sword.
In any of the above cases, the resulting element will appear in the place of the element that you tapped or clicked.
Match swords to attack your enemy, and / or to destroy adjacent stones. Note that you need to click a sword adjacent to a stone to make it disappear. The more swords you combine the bigger the multiplier on your attack is and the more damage you will perform. This means that you should match as many swords as you can to maximize your damage!
