Discover Guriddo: A New Twist on Number Puzzles! Tired of Sudoku? Try Stradoku! Guriddo (グリッド, Japanese for "grid") is a free, competitive number puzzle game with daily challenges. If you enjoy Numbrix, Kakuro, or Kenken-style puzzles and crave a new, brain-bending challenge, Guriddo is for you.

A Word of Caution: Stradoku is highly addictive! Similar to Kenken and Kakuro, you'll fill a 9x9 grid with numbers 1-9. However, black fields add an extra layer of complexity by restricting rows and columns.

New to Stradoku? Don't worry! We offer an easy beginner's guide and puzzles to get you started. (But we warned you...it's addictive!)
