Blokus is a popular board game that involves strategic placement of geometric shapes on a board. While there are no direct synonyms for the name of the game, there are several words that convey a similar concept. For example, "Tangram" is a puzzle game that involves arranging seven pieces into a larger shape. "Pentominoes" are similar to Tangrams but use five squares instead of seven. "Polyominoes" are a more general term that refers to any shape made up of squares, and can include both Pentominoes and Blokus pieces. "Tetrominoes" are a specific type of Polyomino that uses four squares, like the pieces in the game Tetris. All of these games involve spatial reasoning and strategic placement of shapes, much like Blokus.
