Brickosquare stands out in the crowded block puzzle genre (think classics like Block Blast, Woodoku or Blockudoku, which often use 8x8 or 10x10 grids) by offering a challenging 9x9 Sudoku-inspired grid that adds extra strategic depth and space for smarter placements—perfect for players who find smaller boards too restrictive but want more logic than pure chaos. You can also customize your blocks, grid and background. Like chess? Play on a chessboard grid. Compete on leaderboard!
