Response from developer

In the new version we removed ads and moved some features behind a one-time in-app purchase. If you have already purchased, you are still a premium user and do not need to pay again. If you still see paid content after purchasing, please tap Restore Purchases in Settings. If restore fails, contact me via the email option on the Settings page. The new version still has some bugs, and I am working hard to fix them. Thank you for your understanding.

The Best Sudoku App

I play sudoku daily for focus and at times even mindfulness relaxation. Having an app that allows the ability to play without distractions or annoyances and allows me to tailor the app to my personal preferences is what is so great about Sudoku Custom. Thank you for your hard work and your vision in developing this app.

Bug Fixed

They fixed the tutorial bug, rather quickly as well, so I feel obligated to update my review.

The tutorial on this app is one of the best Ive seen. I have 4 sudoku apps and I use this exclusively for tutorial. The tutorial mode alone warrants at 4 stars, but Im giving it 5 because they fixed the bug quickly and the app is relatively user friendly.

Amazing App

Actually one of the best apps out there. It’s great for learning techniques of all levels. I especially like that I can create or import my own puzzle from a book or magazine and get hints that tell me WHAT the next step is and WHY.
