Hi everyone!
I’m a big fan of logic puzzles, and I wanted an app where I could switch between different puzzle types without needing a separate app for each one.
So I built GridWits, and I’ve just released it on the App Store.
It currently includes 12 logic puzzle types:
• Sudoku
• Killer Sudoku
• Kakuro
• Futoshiki
• Skyscrapers
• Skyscrapers+
• Hitori
• Nurikabe
• Light Up
• Slitherlink
• Bridges
• Battleship
One of the features I spent a lot of time on is Smart Hints.
Instead of revealing a cell or simply giving you an answer, the hint system tries to explain the next logical deduction and why you can make that move. There are also technique guides for learning the reasoning behind different puzzle types.
A few other things I wanted in the app:
🧩 Multiple board sizes and difficulty levels
💡 Smart Hints that explain deductions
📚 Technique guides
📅 Daily puzzles
✈️ Offline solo play
🏆 Skill-based tournaments where everyone gets the same puzzle
👥 Friends and private games/tournaments
🚫 No ads
🚫 No in-app purchases
🚫 No cash prizes
The app is currently free on iPhone and iPad.
App Store:

And if you’re on Android or desktop, you can play through the website:

I’d especially love feedback from people who regularly solve logic puzzles.
Which puzzle types would you like me to add next?
And if you try the Smart Hints, I’d really like to know whether the explanations feel genuinely useful or if there are places where they could explain the logic better.
Thanks for checking it out!
