Edit: This app is amazing and I'm still playing it a month later. I shouldn't give it 4 stars because I'm bad and also Hard puzzles get quite tricky later on I love this app and the puzzles are a lot of fun. I do wish the difficulty jump from Hard to Expert was a little more smooth though. Hard has somewhat simple logic and then at Expert, I feel like basically every single advanced technique can show up. It's a bit rough for someone who wants a challenge but can't learn every technique at once

Thank you for your review, We are glad that you enjoy the app. The expert level can be difficult, the main reason the expert level is not gradual is that Expert player like mostly to 'taste' all the strategies. However, there is a strategies section accessible from 'Settings' where you can find explanation of all the strategies + examples.

the ability to add/remove possible numbers in groups pretty much removes all tediousness from the game. and variations are just amazing, some variations combinations really makes you find completely different approaches. I don't want to play regular sudoku anymore. on top of that, if you are stuck, hints give very decent explanations and reasoning, which often help to solve other puzzles as well. advertisements are there, but are reasonable.

My favorite Sudoku app by far! Hard and Expert puzzles are very challenging, but clearly made by people who are passionate about creating interesting puzzles that have elegant solutions. Lots of easy puzzles for beginners as well. Ads are not too invasive, sometimes glitchy, but much better than other apps.
