ABOUT
A little space to think.
Play Suguru is an independent, free puzzle website made for a few quiet minutes of concentration. Open a board, follow three simple rules, and enjoy finding the next number.
The puzzles
Our original collection includes 36 puzzle layouts on 5 × 5 and 6 × 6 boards. Every layout is checked by a solver to have exactly one solution. Daily and practice puzzles use that collection with rotations, reflections and extra starting clues for the more supported levels. Layouts can repeat.
Beginner, Standard and Challenging describe board size and starting clue support. They are not a calibrated difficulty rating. The daily puzzle follows the date on your device; an open puzzle stays in place after midnight.
Made for an unhurried solve
There is no account to create and no leaderboard to chase. Notes, undo, hints and progress saved in your browser are included. The timer counts active play while the page is visible, and stops when you finish.
