C'est mon Fort! is a fun family card game based on memory and strategy. It consists of a deck of numbered cards representing wall parts. Each player must build a wall of cards in ascending order. All the cards are laid face-down on the center of the table. Each player starts a wall with the card numbered 1. On each turn the player chooses a card from the center, reveals it to everyone, and then decides to either keep it and put it on the right end of the wall or put it back face-down. The end of the game is triggered when a player puts a 10th card. The player with the wall with the most points wins the game.
