Quatrainment

Make a 4 by 4 board match a master pattern against the clock, in as few moves as you can. Pressing a square flips a group whose shape depends on where it is: the middle squares flip a plus, corners a triangle along two edges, and edge squares the three around them but not themselves. A timer and move counter keep score, and the game reports both when the board matches.

Controls: The stick moves the cursor; fire presses the square.
