peaceful in here

only problem is that speed demon is a little buggy sometimes but i can resolve it easily by closing and reopening the app. i dont even mind that little bit of friction. it makes the app endearing to me

Great sudoku app!

No ads, all features you need for free and bonus ones (charts, custom icons) with an affordable one off (not subscription!!) purchase. Plus the speed demon setting is my favourite and now I can’t go back to other methods of filling in.
