Intuitive and unique

A great way to learn or get better at sudoku. I thought i was pretty decent, but I’ve been able to learn interesting ways to get better.

Response from developer

Thank you! 🙂 Glad it's showing you some new tricks - even solid solvers usually find a few surprises in the later groups. Happy solving!

Learn strategies

I was solving medium level sudokus but was getting stuck on harder ones. I looked up videos and tutorials on advanced strategies but it was hard to follow them and understand. This app teaches you the strategies and lets you practice those strategies and understand them before moving on to the next one. The hints are great and walk you through the techniques step by step. Awesome app and highly recommend to up your sudoku skills.
