Always plan for combos when attacking. You will have time to change more positions of gems on the board. Always move when you can create a combo attack. If you can, find a match by moving one gem and keeping the other gem available for moving around. You can eventually build a lot of combos using this tactic. At times you will not have a complete deck and one type of color on the board will result in no attack. Never create a match of that color alone; instead, use it to create combos to at least double the effect of your other attacks. If you can create a match of at least five gems during a fight, you will attack all the enemies.
