The Gumball Rally

Two hands race along a row of six gumball machines, buying gumballs with coins. Each player starts with five quarters, five dimes, five nickels and five pennies. A coin buys as many gumballs as it is worth in cents, but a machine holds only 26 and gives just what is left when it runs short. Move to SELL to turn your gumballs back into coins, or to CHANGE to break a coin into smaller ones. Each machine takes ten coins, and the two hands cannot share a place. When all 60 slots are full, or no coin goes in for 30 seconds, the game ends. Your score is the gumballs you hold, plus your money in cents, plus every gumball you received. Play a friend or a computer hand at slow, medium or fast speed.

Controls: Joystick only. Push left or right to move your hand along SELL, machines 1 to 6 and CHANGE; push up or down to choose a quarter, dime, nickel or penny; press a button to put the coin in, sell or change. In a one-player game either joystick plays the left hand; with two players joystick 1 is the left (cyan) hand and joystick 2 the right (pink) hand.
