Description
Guriddo (グリッド, Japanese for grid) is a free and competitive Number puzzle 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 Guriddo a try.

If you have never played the Stradoku logic game before, read this with caution:
Stradoku is a highly addictive number game. Similar to Kenken, Kakuro or other logic puzzle you have a 9x9 grid that you can 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 the Stradoku numbers game, don't worry - we prepared an easy beginner’s guide & number puzzle for you. And always keep in mind, we warned you about its highly addictive grid game nature.

Guriddo offers you:
- Everyday we release a new number game (daily puzzle challenge)
- Track your solving time and compete against other players (leaderboards)
- There are 5 different difficulties (easy to diabolical)
- Add your friends and play with them a numbers puzzle
- Take a break from the daily puzzle challenges and select your own number game difficulty (tea break)
- Packs with hand-selected logic puzzle (e.g. for beginners)
- Guide with solving strategies
- Profile with stats about your skill level & progress

Recent changes:
- Update 😋: Some contrast and font size optimizations.

Comments on Guriddo: Stradoku Number Game for Android

★★★★★ Andrew S · Nov 28, 2023
A great evolution on the sudoku formula that makes it approachable to beginners, even more so than regular sudoku. Also, a masterclass in ethical monetization. Sometimes my progress doesn't save for games offline, but the bulk of the game is doing daily and weekly puzzles.
★★★★★ Tõnu Uustare · Jun 6, 2025
The best number puzzle game in my opinion, since it takes the good parts of Sudoku and adds a twist which makes it less tedious to find the next step. It also can break down a half-solved puzzle and teach you the necessary strategy to find the next step if you're stuck, which is very handy. The daily puzzles usually don't take up too much time, but still provide a challenge and the difficulty ratings provided by the community can give you an idea of how long it might take to solve one.
★★☆☆☆ Gabriel Costa · Apr 5, 2023
The game is amazing, but I think you need to rethink your business model. I understand the recurring costs of leaderboards, but I honestly don't care about the social features. If I could pay you once to play the game as it was a while back, but with no leaderboards, I would do that. Paying monthly for a feature I don't use at all is not an option for me. The limitation on checks and how many times I can play the daily challenges made the game unplayable for me.
★★☆☆☆ Breanna Granger · Mar 16, 2023
Love the game, but hate the pay (or watch ads) to play format. If be fine with a one time price on this game but paying every week/ month/ year is ridiculous. Probably won't keep this app long due to this format
★☆☆☆☆ Ryan Haran · Jul 31, 2026
Redesign is incredibly ugly and unnecessary, this isn't even the first time you guys have chosen to redesign one of your games for no reason just for it to end up looking worse
★☆☆☆☆ Steve Mattison · Dec 10, 2024
I was told explicitly that these puzzles would not have an ambiguous situation with two doubles in four squares at right angles, but the last free beginner pack (3), puzzle 9, has a 7/8 grouping in the upper right that does this exact thing. EDIT: Not sure how to give you screen here, but still, beginner pack 3 puzzle 9. I'll look into finding it for you...
