Gems Twist : In this game there will be a grid of gems and you will need to destroy the gems by forming lines of 3 or more gems. You can rotate 4 gems in the clockwise or counter clockwise direction so that some gems will be lined up and then they will be destroyed. When a certain number of gems are destroyed, you can advnace to the next level, but if you fail to do so before the time limit, then you lose the game. Click the gems to rotate them, and click the arrow buttons or press the spacebar to switch the direction of rotation.
