Cross Sums forever!

I truly enjoy this app. The only improvement I would like to see would be a help feature where I could learn some more advanced solving techniques. This would be a huge undertaking. The skills included in the app are the standard ones, but where there are many options for learning advanced sudoko techniques, I find very limited options for advanced Kakuro techniques. I can solve the hard level with time but sometimes get stuck on the hard plus level. I need new techniques before I try the truly challenging puzzles. Update! I love being able to use hints when I am truly stuck! Thank you. I would like a few tweaks. Once I’ve filled in lol the pencil marks on my own, if I turn on auto fill it adds possibilities I have already eliminated. Since I can’t use the hints unless it is on, I then have to remove lots of options I have a lady eliminated.

Best version of a great puzzle game

First, Kakuro is a great puzzle game in its own right, much more fun than Sudoku in my opinion. I like it because it is a number and logic puzzle, whereas Sudoku is strictly a logic puzzle. Second, Conceptis has combined quality puzzles that are accurately graded for difficulty with a flawless user interface and a never ending supply of new puzzles to produce the best Kakuro app available. Conceptis began publishing great Kakuro books in 2006 and with this app has continued with the same quality and grading system digitally. Beware, once you develop some skill, Kakuro is very entertaining and you can easily get hooked and waste an incredible amount of time. Highly recommended. I did suggest a couple of improvements, one of which I have seen in another app. It would be helpful in solving if you could either enter color coded pencil marks, or if you had the option to place pencil marks in the order in which they are entered. So far, they don’t seem inclined to implement either of these suggestions.

Fantastic for number logic fans

First the nitpick: There is a learning curve to a point, especially if mental math is not your forte. Learning the “Kakuro block” combinations will help immensely if you’re a new player. Other than that, if you are a fan of these things, run, do not walk, to this app. Not only are the puzzles appropriately graded for difficulty, but you get a huge array of starter puzzles to help you figure out the difficulty that’s right for you. There is also a new bonus puzzle each week and new content, all reasonably priced, is added regularly. Being able to check your grid as many times as you want to is also very helpful. The quality of this is a close second to famed Japanese puzzle makers Nikoli for puzzles that are challenging but fair no matter what your skill level. There are many other Conceptis apps, so there is a good chance that you will find the kind of logic puzzle that suits your fancy. Recommended on all counts!
