Match Mania

A spot-the-difference game. Four framed boxes, numbered 1 to 4, fill with the same pattern of look-alike symbols, except that in one box a single character on one line has been changed. Find the odd box out and pick it. A wrong guess brings SORRY... TRY AGAIN, adds 45 seconds to your time and marks that box NO. The right one shows CORRECT!, says which line and character are different, marks it in all four boxes and flashes the odd box, then shows your guesses and time. You choose the pattern size first, characters per line and lines per box. A game runs through eleven sets of symbols. One player wins with 75% correct or better; two players are ranked by time or by percentage correct, with a results table at the end.

Controls: Use either joystick. On the title, push up and down to choose a line, left and right to change it, and press a button on START or CREDITS. In the game the stick moves the yellow frame to a box and a button guesses it.
