This is a print-and-play board game (including a game board, but you'll need to supply some simple pieces of your own), in which players play at a fictional ball sport known as Backscore - something a little like soccer, but the idea is to move the ball into your own goal (think: Capture the ball, or 'bring it home').

Gameplay is rapid, and comparable to a more complex and progressive (in the sense that 'number of moves' grows) Neutron, which was the base game that Backscore developed out of (it's changed enough now to be a whole other game, but the roots are visible and the credit deserved).
