The player is presented with a grid pattern composed of flat shapes of varying size and color, which forms the foundation of the game. The object is to fit seven distinct geometric shapes, known as tangram pieces, into the grid by rotating and moving them around until each shape perfectly fits inside the grid pattern.
The player has to manipulate the tangram pieces by rotating and moving them in position, using a skill that is a combination of spatial reasoning and problem-solving abilities. The challenge lies in figuring out how to fit each piece perfectly into the grid pattern without leaving any gaps or overlaps.
Players can move and rotate the tangram pieces in the grid, and the game does not have any time limits or obstacles except for a given size grid, so players can focus on finding the solution at leisure. The game runs in the browser, requiring no downloads or registration to play, making it easily accessible to all players.
