Victory Point (One-Eyed Jacks)
Victory Point is a medium-length format, a compromise between Elimination and Total Control.
In a Victory Point game, a player wins by earning a number of “victory points” equal to their number of opponents (ex. 2 victory points for a 3-player game). Earning a victory point is accomplished in the same manner as eliminating an opponent (using the Elimination rules), but instead of their opponent being eliminated, the player gains a permanent victory point instead. Victory points roll-over and accumulate as the game progresses. If two or more players meet this win condition at Sundown, before resolving tie-breakers normally, the player who has accumulated the most victory points wins.
