## Most critical reviews (8 lowest-rated)

### 3/5 — Quite handy

*2011-12-02, version 1.0*

It would be much better if the sums went all the way up to 45 (not stopping at 39!) and the digits up to 9 (why stop at 6?).

### 4/5 — Does what it should

*2013-04-22, version 1.3*

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.

### 4/5 — Cross off

*2013-03-01*

The only thing I would change is to have the ability to cross off the combinations that don't work

### 4/5 — Looks promising

*2012-08-01*

Don't know whether I'll use it but it looks fine; What do you mean by "Allow double" (no game allows That) ?

### 5/5 — Brilliant little app

*2022-05-05, version 3.0.2*

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!

### 5/5 — Amazing

*2021-10-04*

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.

### 5/5 — Killer sudoku toolbelt!

*2014-03-31*

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.

### 5/5 — Get out of Jail card

*2013-06-07, version 1.3*

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.
