Sometimes the pellets hide underneath the score counters. First vacuum to suck up 50 pellets wins! Green score is on the right, orange is on the left. The vacuums spin around on their own until you press the forward key (W for green, up arrow for orange). Moving near pellets picks them up. 10 more pellets appear after all of the pellets on screen are gone and repeats until one player has 50. Press the green flag to restart.
