Brilliant little app

I am a Killer Sudoku addict….this is the most useful helper I’ve ever seen. Does exactly what it says, and saves me time looking up combinations. Easy to use, quick, reliable - and no ads. Excellent!

Amazing

This app is perfect, exactly what I was looking for to aid me in solving kakuro puzzles. Thank you so much for creating such a straight forward app that does exactly what I need it to without any annoying ads.

Killer sudoku toolbelt!

I do killer sudoku puzzles frequently. Having the combination sums handy let's me focus on the puzzle.

For the last couple of years, I have planned on building an app for that. When I sat down to start last week, my research led me to 12 in 3, which had EVERY element of my design.

No reason to reinvent the wheel. Well done. Well done.

Get out of Jail card

Brilliant. I'm frequently bamboozled by the more complex combinations and this really helps - the get out of jail card, so to speak. Excellent app.

Does what it should

Does what it says in an easy to use way. Could do with the addition of a calculator though. Also would be nice to get combinations for 8 and 9.
