About this game

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.

Ratings and reviews

It's a decent puzzle game - but it would benefit a lot from quality-of-life UX improvements. (Example: when I'm sure there's a 3 in a cell, I'm then sure there's not a 3 anywhere else in the same row or column, but I have to clear my pencil marks manually.) Good sudoku apps automate this process, which otherwise take up much of my time playing this game in a very uninteresting way.

Added a star because now there is an "undo" button! It would still be helpful if you could mark just one potential number in a square. That way, you could mark two squares in a row or column with the same single number, to show that that number can only belong in one of those two squares. Similar to most Sudoku apps. But it's a challenging game, and I hope updates will improve the playing experience.

Brilliant, straightforward puzzle game. There are perpetual banner ads, but they are generally unobtrusive, and there are no ads between levels. There are thousands of levels of varying difficulty, and the puzzles require only logic and basic math to solve. My only minor complaint is that the number buttons are right at the bottom of the screen, so I tend to hit my phone's back button by mistake.
