Gems Twist
The goal of the gems is to blow up gems. You do so by forming lines of 4 or more identical gems.
When you click on a set of gems, you rotate 4 of them clockwise or counter-clockwise, helping you form a set of gems in a row.
Click the arrow buttons on the left side of the game or press spacebar to switch the direction of rotation.
You can advance to the next level when a certain amount of gems is destroyed but if you fail to do so before the time limit you lose the game.
