Speed Match Review Game

This game has been played times
The best time ever was at seconds.
The best time today is at seconds.
How To Play:
Drag the squares in the gray area and drop them in the matching squares in the blue area below.
If you drop a square in the correct spot, it will disappear.
If you make a mistake, the square will return to its original spot.
Good luck!
