A small polish update: - Finished a puzzle with the timer hidden? The completion screen now offers a "Show my time" button — and lets you save it as a best time if it qualifies. - Check now shows "No errors found" when the grid is clean. - New keyboard shortcut: "C" toggles the calculator (iPad). - Subtle haptic flourish when you complete a puzzle. - Various small UX improvements. Thanks for playing!

Sudoku newbie

As someone who has never played sudoku, I found this game to be fun, exciting and a great way to learn the game! It looks like it will keep me engaged as my skills grow. I can’t wait to see what comes next!

Great game

Sudoku if it was awesome

Sudoku done right!

I don’t usually write reviews, but this app forced my hand — in a good way. Imagine if Howard Garns, coffee, productivity, and pure genius had a digital baby — that’s this app. It’s a no-nonsense gem that strips Sudoku down to its addictive core — simple 6x6 grids with clever cage sums, no bloat. Just pure logic puzzles that hook you fast.

The interface? Smoother than a dolphin wearing sunglasses. The features? So intuitive my dog could play (and she’s terrible with technology).

If you want an app that actually does what it says, looks great while doing it, and maybe even raises your IQ a few points grab this one!

Really cool game!

I had fun playing this even though I was new to playing. It was so easy to understand. 😆

Killer sudoku

A great game. Good instructions. I love the pencil marks. The circles help the numbers stand out a bit. You can even select the color of the board! I'd give 6 out of 5 stars if I could.
