Our take on the STG The Genius Square

The Genius Square is a head-to-head spatial puzzle game. Each round, seven blocker pieces are placed on a 6x6 grid, and players race to fit their set of Tetris-like shapes around them and fill every remaining space. The blocker dice create over 60,000 starting layouts, so no two rounds repeat. It suits families, puzzle fans and classrooms that want a fast, low-rule brain game; against single-player logic puzzles it adds a live race, and against chess-style abstract games it is quicker to learn and far shorter per round.

About the STG The Genius Square

The blocker pieces go into different spaces each round, so the puzzle changes every time. There are over 60,000 possible puzzle combinations.

Two players can race to see who fills their board first. One player can also play alone against a timer.
