About Sufuku
Sufuku is a daily logic puzzle played on a 6×6 board where each number appears exactly as many times as its value. On the standard board, each row contains one 1, two 2s, and three 3s. This constraint applies to every row, column, and region of the puzzle.
Each puzzle has exactly one solution and requires pure deduction with no guessing. The gold numbers on the board serve as clues to help solve the puzzle. A new puzzle is released daily at 2:00 AM, with difficulty increasing throughout the week—puzzles are easiest on Monday and hardest on Sunday.
