The best I've seen – KakuroX Review

Haven't seen any 10 minute generation times - the longest has been 3 minutes for a 9x9 puzzle on an iPhone 4. This is still too long. However, I personally like to do 7x7 puzzles, because the squares are too small for 8x8 and higher. A 7x7 puzzle is generated in 4 seconds or less, which is acceptable to me. Easy and fast interface makes this the best Kakuro. I have found the Medium and Hard puzzles to be much more challenging than the so-called hard puzzles on another product.
