Match 3 games never seem to get old. They all share the same basic gameplay, but they're so addictive and easy to add different twists. In Gem Swap 2, you have to match 3 or more of the same gem and the blocks occupied will be lit up. You will pass the level once all of the blocks have been lit. But, you have to hurry up, because there is a time limit and it's working against you. See how many levels you can beat and how high you can get your score.
