Qwirkle is a tile-based game for two to four players, in which players score points by creating lines of tiles that share a common attribute, such as color or shape. The game is played on a grid, and players take turns placing tiles on the grid, trying to create lines of their own while also blocking their opponents from scoring.
Qwirkle was invented by Susan McKinley Ross in 2006, and it has since become one of the most popular board games in the world. The game has been praised for its simplicity, its strategic depth, and its replayability. Qwirkle has also been used in educational settings, as it can help students to develop their problem-solving skills and their spatial reasoning abilities.
