Kakuro is one of the oldest logic grid puzzles. Kakuro is like a crossword puzzle with numbers. Each word must add up to the number provided in the clue above it or to the left. A given number can only be used once in a word. Every kakuro puzzle has one and only solution, and can be solved through logic alone. Dot Kakuro is a new variant of Kakuro puzzle. No digit can be duplicated in a row or column. If difference between two numbers in neighboring cells equals 1, then they are separated by a dot. If a dot is absent between two white cells, the difference between the numbers in these cells is more than 1. **** Kakuro Challenge features **** # Content - 5 difficulty levels for standard Kakuro puzzles - 3 sizes for Dot Kakuro puzzles # Features - Cheat sheet helps you to solve the puzzle - Pencil mode - Hint feature - Autosave the process of unfinished levels - Record best completion time for each level ## Key features - Standard Kakuro puzzles - Dot Kakuro variant - 5 difficulty levels - 3 Dot Kakuro sizes - Cheat sheet - Pencil mode - Hint feature ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Kakuro Beginner Pack | $0.99 | one-time | | Kakuro Median Pack | $0.99 | one-time | | Kakuro Advanced Pack | $0.99 | one-time | | Dot Kakuro Mixed Pack | $0.99 | one-time | | Dot Kakuro Size 10 Pack | $0.99 | one-time | | Dot Kakuro Size 11 Pack | $0.99 | one-time | | Dot Kakuro Size 12 Pack | $0.99 | one-time | ## Recent user reviews (10 of 20) All indexed reviews: https://appshunter.io/ios/app/kakuro-challenge-cross-sum/id1185788482/reviews.md ### 4/5 — Great game poor layout *2024-08-26, version 1.0.15* I love this game. Used to play it years ago on paper and delighted to have found it again as an app. I tried several Kakuro apps and this is by far the best for playing, and ads are not too intrusive. The only thing that lets it down is the layout. I’m playing on a phone so making best use of screen space is important. The puzzle is at the top, plenty of space. Then there is a lot of blue background space, with the number pad plus other controls squeezed into the bottom fifth along with a fairly large Menu key. So the numbers are quite small and fat fingers have difficulty. It would be very much better if the number pad took the full width further up the screen, giving the other controls more space too. I’m keeping going because otherwise it’s great, but I hope you can do something about this. Thanks. ### 5/5 — 初級は面白い *2024-03-13, version 1.0.14* 面白くて、病みつきになりそう！ ### 4/5 — Great but not enough puzzles *2023-10-06, version 1.0.14* This was my favorite Nakuru game but it has a limited number of puzzles. After you solve all the free and the paid puzzles your only option it to do the previously solved puzzles over again. They haven’t added any new puzzles. ### 5/5 — Good game *2023-07-29, version 1.0.13* Great brain game. My only complaint is that the keyboard is not easy to use, needs a fair bit of pressure, so makes it slow. ### 1/5 — Numbers not working *2023-05-20, version 1.0.13* Great game, but the numbers mainly 123 do not work most of the time. ### 1/5 — Too easy, extreme done in 2:36 and no big puzzles *2021-11-04, version 1.0.12* Avoid ### 5/5 — Great app! *2021-01-10, version 1.0.11* I downloaded dot Kakuro because it reminded me of kropki. Dot Kakuro is fun to play and is one of my favorite number games. ### 5/5 — Very easy to use *2020-07-22, version 1.0.10* Much more convenient than by paper and pencil ### 4/5 — Kakuro *2020-01-26, version 1.0.9* Love playing this game. Will miss it when the free games are completed! ### 5/5 — Yay!! *2019-08-20* Exercise mind while passing time. 🦋🤣🌹 ## Frequently asked questions about Kakuro Challenge ### What is Kakuro Challenge?
