Point Guard is a basketball game about decimals. The ball is the decimal point: dribble it left or right and watch every digit shift on the jumbotron. Warm-ups show how it works, Drills build numbers and move by powers of ten, the Scrimmage asks for an estimate before placing the point in a product, and the Championship uses real prices and sizes.
A missed shot tells you what number you made and whether it is too big or too small, then you adjust and shoot again. Nothing is timed. Skip ahead with a three-shot tryout.
