A Game of Wits and Cunning 7 colors. 7 numbers. 49 cards and infinite ways to play. In Red7, the goal is not to follow the rules, but to win. In order to do so, players who can't meet the standing requirement can change the rule and force their opponents to obey it. This simple twist makes Red7 as unpredictable and exciting as an action game, while preserving its deeply tactical essence. Source: The Developer Website.
