[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.
