Update Ur App! *2025-02-15, version 5.2.7* This was my all-time favorite app, but after the most recent update, it is so huge on the screen of my iPad, I can’t even play it. There are no setting options to get it back to how it was. So disappointed. ### 1/5 — Crashes *2025-02-14, version 5.2.7* 14/2/25 I used this in the past on my iPad (air2) and never had a problem. Put it on iPhone 15 and it constantly crashes when wanting to use hint, save and exit etc. Basically once a game loads from the main menu you have to play it without using hint or anything in the menu. Tried all the usual fixes, restarting ph, uninstalling-reinstalling several times. Can it be fixed - 🤔 ### 5/5 — GLAD YOU'RE BACK⭐️⭐️⭐️⭐️⭐️ *2025-02-05* Great app! Makes a great game greater with lessons on different solution elements on levels from beginner to really, really, really tough! It's a big thing to me to be able to capture a puzzle from a photo or a scan. Love it! Still love it! I’m back to say it’s still a great app. What I said previously still holds true. One of only two games on my phone, so it has to be tops! FOLLOWUP: This has everything I like in an app. Still tops! ANOTHER FOLLOWUP: Still a wonderful game. It's now the only game on my phone! The best! ### 3/5 — Doesn’t work with new ipad 😕 Is there a fix? *2024-12-28, version 5.2.7* Is there a fix? ### 5/5 — Joyful Sudoku *2024-12-18, version 5.2.7* I love this version with so much help that helps me learn to solve the puzzle more. And I appreciate your long list of daily puzzles. ### 5/5 — Best sudoku app I’ve ever found *2024-12-16, version 5.2.7* Allows you to tweak it in so many ways—tons of options for play at various levels and totally teaches you as much as you want to learn. Easy to use. The Best. ### 1/5 — Unplayable *2024-11-27, version 5.2.7* For over 12 years this was my favorite game. After installing the latest iOS it became unplayable. Emails to the producer went unanswered. Delete and reinstalling had no effect, or made it worse. I’m really sorry to see this go, but there’s no point to it now ### 5/5 — I really enjoy this app! *2024-11-26* This is one app I come back to time after time. I love how simple and intuitive the game is to play. The challenge of different levels works for me, since on days I want to relax I play easier levels and when I want to challenge myself there are always the harder levels. Sudoku is a game I enjoy while not being gifted at. When I master a new level, that is solve it without using hints at all, I feel a sense of accomplishment. I’ve even managed the simpler levels without using pencil marks! ### 5/5 — Love that it helps me learn *2024-11-26, version 5.2.7* I appreciate the different settings that let you play the way you wish to. I really like the hints that help me learn how to solve the harder puzzles. After a fairly short period, I am getting better at solving them because of the hint that offers the option to learn what to look for. ### 5/5 — Game display with IO 18 *2024-11-24, version 5.2.7* The game display is now off with the latest apple update. Please fix. ## Frequently asked questions about Sudoku Joy ### What is Sudoku Joy?
