Guriddo (グリッド, japanese for grid) is a free and competitive Straights app with daily challenges and a modern look.

If you have never played Straights before, read this with caution:
Straights (or Straduko) is a highly addictive logic-based math puzzle. Like Sudoku you have a 9x9 grid that you need to fill with numbers from 1 to 9. To increase the difficulty, rows and columns are additionally limited through black fields. But see for yourself!

If you are new to Straights we prepared an easy beginner’s guide for you. And always keep in mind, we warned you about its highly addictive nature ;)

Guriddo offers you:
- A new puzzle everyday
- Compete against other players by seeing who solved the puzzle quickest
- We offer 5 different difficulties (easy to diabolical)
