Easy game to play, and by easy we mean it might take you all but 5 minutes to figure it out and complete it. The only way this game is functional is if you are a 3rd grader learning math, and even then you will get bored with it.
Given the time of June 1986 and NES has no other games other than the release titles in October 1985. This was a filler and an easy on at that, because it used the same coding as Donkey Kong Jr.
