Neutron

1. Each turn, first move the neutron (white) in any direction. It slides in a straight line as far as it can until it hits the edge or another piece — it cannot stop short. The very first turn of each game skips this step.
2. Then move one of your tokens the same way: as far as it can go until it hits the edge, another token, or the neutron.

Win by getting the neutron onto your opponent's starting row, or by trapping it so it cannot move. Careful: if the neutron lands on your own starting row, your opponent wins. First to 3 wins takes the match.
