How to play

  1. On your turn, choose any unclaimed number. You score that number.
  2. Your opponent scores every proper factor of it that is still unclaimed — every divisor except the number itself.
  3. You may only choose a number that still has at least one factor left. Numbers that don't are dimmed.
  4. The game ends when no legal move remains. Numbers still on the board score nothing.
  5. Highest total wins.
