Kropki is a logical puzzle game. In this game you have to fill the playing field with numbers, initially all numbers are missing. Fill the field so that the following two conditions are met: * All numbers in the rows must be unique. Every number in the row occurs only once. * The same rule for columns, all numbers must be unique. Also there are additional conditions, on the field there are white and black dots: * If there is a white dot between two cells, then the values ​​in these cells differ by one. * If there is a black dot - then the values differ by half. For example (1 and 2, 2 and 1, 2 and 4, etc.) * All possible dots on the field are already exposed, this means that if there is no dot between the two cells, then their values ​​can not differ by one and can not differ by half. Note: For numbers 1 and 2, there may be both white and black dot in neighbour cells. Because both rules are observed. In the process of the game, for your convenience, you can put more than one number in the cell, and in after remove the numbers that do not fit. The level will be considered passed if all cells have only one digit and all the above conditions are met. In the program you can choose one of six difficulty levels. If you've never played in Kropki. Try to start from the first level on the 4x4 difficulty. ## Key features - Fill grid with unique numbers - White dot: adjacent numbers differ by one - Black dot: adjacent numbers differ by half - All dots are shown - Multiple difficulty levels - Supports multiple numbers per cell during play ## Recent user reviews (10 of 25) All indexed reviews: https://appshunter.io/ios/app/kropki-puzzle/id1390431292/reviews.md ### 4/5 — Good game - could improve playability *2024-10-17, version 1.6* The game is very good, and also I like that while there are adverts they’re not intrusive and don’t destroy the experience. There’s a lot of content here, so there are hours of entertainment. I feel that the game play is a bit clunky - something as simple as an eraser function would make things easier. It would be also good if you could highlight more than one cell to lay down numbers. But that all said it’s still a fun game, and excellent value. ### 5/5 — Great puzzle *2024-09-07, version 1.6* As you proceed through the different levels you have to find different strategies to solve the puzzles - so it doesn’t get boring. ### 5/5 — Very good *2023-12-15, version 1.5* Great challenge for the mind. So many games at each difficulty level. Maybe add some warm contrasting colors. Took awhile to get skilled at 9x9 but now that I recognize some useful patterns it’s so satisfying. ### 5/5 — Fun puzzle, doesn't save *2022-11-22, version 1.3* I really like this style of logical puzzle. No guessing necessary. But it always loses the save! I'm tired of losing my progress. There doesn't seem to ever be updates so I guess this is as good as it will ever get. Which is a shame because there's real potential here. ### 5/5 — Поправили скорость ответа *2022-04-20* Спасибо разработчикам за игру и за новые релизы с улучшением производительности! ### 5/5 — Strategy? *2022-04-19, version 1.3* Excellent game, but I’m struggling to get started on the 8x8 and beyond. Any strategies? ### 4/5 — Very good *2022-03-02, version 1.2* Great challenge for the mind. So many games at each difficulty level. Maybe add some warm contrasting colors. ### 5/5 — Brilliantly simple, simply brilliant *2022-01-02, version 1.1* Puzzles with simple rules that vary from quick and easy to fiendishly, mind meltingly difficult. Absolutely love these puzzles! ### 3/5 — Ganz nette Unterhaltung fürs Gehirn *2021-12-17* Spiel ist eigentlich gut. Aber die App stürzt manchmal ab. Dann muss man wieder bis zu dem Level scrollen, wo man aufgehört hat. Das kann bei Level 900 ganz schön dauern. Deshalb nur 3 Sterne. iPhone 6s und iPhone SE (2020) ### 5/5 — Finally a challenging game *2021-11-05* Strong logic skills needed for higher level games. I like it. ## Frequently asked questions about Kropki Puzzle ### What is Kropki Puzzle? Kropki Puzzle is a logic game where players fill a grid with numbers. The core rules involve ensuring all numbers in each row and column are unique. Additionally, specific dots between cells dictate relationships between the numbers they separate. ### How do the dots work in Kropki Puzzle? White dots indicate that the numbers in adjacent cells differ by exactly one. Black dots signify that the numbers in adjacent cells differ by half (e.g., 1 and 2, or 2 and 4). All possible dots are present, meaning no dot implies the numbers cannot have these relationships. ### Is Kropki Puzzle free to play? Yes, the game is free to play.
