Crystal Clear trains strategic thinking and spatial visualization skills.
To begin, click the Medium link above. This opens the game in a pop-up window. Wait for the game to load, then click the "Start Game" button.
Note: This game is only available in Medium size.
| The object of the game is to clear out the colored crystals before the board becomes full. 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!
