7 Wonders Duel is a two-player strategy board game that is a spin-off of the original 7 Wonders game. In this game, players compete against each other to build the greatest civilization by acquiring resources, constructing buildings, and developing military strength. The game is played over three Ages, with each Age consisting of three rounds. Players take turns choosing cards from a common pool and using them to further their own civilization while trying to sabotage their opponent's progress. The game ends when one player achieves a military or scientific victory, or when all the cards have been played.
