Well worth the price – KakuroX Review

This is definitely one of the most used applications on my iPhone. The app is flexible allowing you to create large and small puzzles varying in difficulty. Unlike similar apps, KakuroX does not have a list of standard puzzles which are repeated over and over but generates new ones on the fly. As other reviews mention, the largest puzzles take a long time to generate. The process also is taxing on battery life. But as long as you don't exceed 7x7, it usually returns reasonably quickly. I have not encountered any unsolvable puzzles as other reviewers suggest. KakuroX is definitely one of my favorite time wasters.
