It keeps saying I’ve lost. Lost what?! I completed the puzzle...what more did you want?? ### 4/5 — Good app but not validating more than one solution *2020-06-22* Hi can’t there be more than one solution to A sudoku. The app validates to match again just one predefined solution n not against the sudoku rules ### 3/5 — Glitch *2020-06-04* Seems to be a glitch with the expert levels, have been mostly filled out already when I have only just unlocked the puzzle. Taking less than 30 seconds to solve. Please fix. **Developer response:** Thanks for the feedback, there seems to be an issue with some of our levels -- we will fix in coming days! ### 1/5 — You lose despite completing the puzzle correctly *2020-05-14* Multiple times have I completed puzzles just have it say you lose. This game is broken and not worth the time. And you can't play on multiple devices and have your progress carry over (iPhone to iPad). NOT WORTH IT !!! **Developer response:** Thanks for your feedback! We'd love to better understand which level you are seeing this for, please reach out to us at hello@matchalagames.com so we can assist you. Also, syncing across multiple devices is something coming soon! ### 4/5 — Simple and fun *2020-05-13, version 1.10* I love the way it allows me to play according to Level and the Easy, Medium and Hard Mode allow to challenge me. No reward system which is okay 👌 ### 1/5 — Too easy *2020-05-12* Yeap, just that **Developer response:** Heya, thanks for your feedback! Have you tried to play on our Hard or Expert game modes, we've been told my advanced players this even gives their brain quite a tickle :) ### 2/5 — Makes you restart if you hit a wrong number *2020-04-29* This game is good but if you make any mistakes you can’t fix or change it. You have to completely restart the level **Developer response:** Heya! Thanks for your feedback. There's actually an option in the setting which allows you to turn our "Mistake Limit" off, but because it's a bit hard to find we've disabled it by default! We hope you'll try our game again :) ### 1/5 — Game crash *2020-04-24, version 1.0.7* Game crash on level 2 pfft ### 5/5 — Awesome sudoku *2020-04-18* Very cool game with many different levels to keep your brain sharp and functioning well! ### 1/5 — What a bad app! *2020-04-18* I have played sudokus and this is one of the worst app. You can make notes but cannot delete these notes. Plus couple of games when i put the last correct piece it says lost! Does not allow you to see what was wrong or point it out in the app- just says lost! Deleted this app **Developer response:** Hey! Thanks so much for your feedback, we actually took this to heart and implemented all of your feedback in the latest update. We've now fixed the pencil mode issue, made sure there's only 1 solution per level AND turned off "Mistake Limit" by default so you can have more mistakes. We hope you will try, but if not we really do appreciate your thoughts, cheers! ## Frequently asked questions about Sudoku Brain ### What is Sudoku Brain?
