The game was made in April 2003 to coincide with the first long-form season of Oobi. It was part of a series of four matching games, the others being Rhyme, Letters, and Remember. These four games were meant to teach basic retention skills. The earlier games from 2002 were simpler and didn't have much educational value.
"You can count on Oobi to teach you how to count out shapes. Oobi will count out the number of objects in a set. Oobi then gives four possible answers. You will count the objects to find the right answer and then click on it. Get it right and win a star. Get three stars and you win the game! Play as often as you like!"
All of Oobi's sprites are reused from earlier games.
