In this very simple abstract game players place pins with hidden numbers from 0 to 5 on a 6 by 6 board. The highest added 'line' of numbers by one player, interrupted or not, diagonal or orthogonal, wins after all pins are revealed at the end of the game. The hitch: any '0' in the line, your own or by any other player, nullifies all numbers, making the line worthless. Advanced rules introduce betting in the possible outcome, so you might win a series of games by guessing who placed best in each game. - BoardGameGeek
