Checkmath is a board game published in 1968 by Grant Trading.
Checkmath is a game in which numbered counters are placed on opposite sides of a ten-by-ten squared board also marked with numbers, and players take each other's pieces by landing on spaces occupied by their pieces.
Eric Solomon reviewed Checkmath for Games International magazine, and gave it 2 stars out of 5, and stated that "Checkmath is one of those games which an educationalist might applaud, but it bored me stiff. I will concede that it might be a good idea to play it several times with a six year old child, but after the age of seven it should be used only as punishment."[1]
