About Guriddo: Stradoku Number Game
Guriddo (グリッド, Japanese for grid) is a free and competitive Sudoku alternative with daily challenges. If you enjoy playing Numbrix, Kakuro or Kenken style like number puzzle and seek a new tricky challenge, then you should give Stradoku a try. If you have never played Stradoku before, read this with caution: Stradoku is a highly addictive logic-based number puzzle.
