Crystal Clear Instructions

You make crystals disappear by moving crystals around until five or more of the same color are touching.

Use your mouse to move the crystals. To move a crystal, first click the crystal then click the square where you want it to go.

OTHER RULES.  You cannot move a crystal if there is no free way to the destination square (that is, if the path is blocked). Broken crystals explode and clear the area around them. You can move a heart next to a group of crystals to color them. You cannot move "locked" crystals.

This game quickly gets challenging and really gives your brain a workout.

Have fun!
