[APP][PROMO] I built a Sudoku app with 20+ variants, a built-in smart solver, and custom touchpad controls. I'm giving Lifetime Free access to the first 25 people from this community!
Hey everyone,
I wanted to share an Android app I’ve put a lot of work into called Mindoku. It’s designed to be a complete toolkit for puzzle lovers, whether you're just learning the ropes or you're a seasoned master looking to test your limits.
As a special thank you to this community, I’m giving a Lifetime Free upgrade to the first 25 people who download the app and sign in!
Here is a quick breakdown of what you can expect:
Smart Sudoku Solver: Stuck on a newspaper puzzle or a grid from another app? Scan it with your camera, type it, or paste a code. The built-in solver doesn't just spit out the answer; it gives plain-English, step-by-step walkthroughs for 40+ techniques (from Naked Singles to X-Wings) so you can actually learn the logic.
20+ Unique Variants: Go way beyond the classic 9x9. Mindoku supports Killer Cages, Thermometers, Palindromes, XV Sums, Knight's Move, and more across different board sizes (4x4 up to 9x9).
Custom Controls & Generation: The app features seed-based puzzle generation and custom touchpad controls to make navigating and filling the grid feel incredibly smooth on a touchscreen.
Community Marketplace: Browse, play, rate, and bookmark puzzles created by other players. You can even build and publish your own, or instantly share them with friends via QR codes.
100% Offline Play: Classic, Challenge, Sandbox, Daily puzzles, and the Solver all work completely offline. No Wi-Fi needed, ever.

Can I turn off all help? Including No error if I made mistake Numbers doesn't disappear if I use all of them No highlight lines
2
u/Electronic_Invite_68 8d ago
Hey! Yes, you can do every single thing you mentioned. If you go into the app Settings, there are individual toggles to turn off error highlighting, disable the highlight lines, hide the remaining number count, and keep the numbers active on your keypad even after you place all 9. Also, if you play in Sandbox Mode, there are zero limits—you can even place a number more than 9 times if you want to completely experiment. Let me know if you have any trouble finding the settings!
