I will not purchase as the layout of the game is not suited for my screen because the number 9 falls off the bottom. **Developer response:** Hi, thanks for bringing this to our attention. We just shipped a new update, can you check if that fixed it for you? If not, do you mind telling us what device you are using? Thanks for your help! Shoot us a mail at info@devloft.de and we'll hook you up with the full version for free. ### 4/5 — Decent play for ad free *2025-03-19* So refreshing to actually get to play without constant interruption by ads. That said, this app only has Medium and Easy levels for free (and medium was fairly easy). For more difficult levels you need to pay. Also Dynamic Type isn’t supported. I had to decrease my phone setting text size so I could see and use the number 9. ### 1/5 — Not quite right? *2024-10-19* I switched to this after using another Sudoku app for many years. The number 9 is missing from the solutions. So every time the correct answer is a 9 I have to use “help”. Quite frustrating. Why does it only have 1-8 when clearly the 9 is used in the puzzle as well. Very poorly designed ### 3/5 — Screen layout does not permit to use 9 *2023-07-11* Nice game, no ads but only beginner and medium levels are playable without further purchase. I will not purchase as the layout of the game is not suited for my screen because the number 9 falls off the bottom. **Developer response:** Hi, thanks for bringing this to our attention.
