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 lets me play Kropki smoothly and easily. I would love to see a feature where if I have a bunch of possible numbers entered for a cell, and I figure out which number is correct, I can double tap the correct number rather than having to unselect all the wrong ones. That is, however, the most minor of nitpicks. Even as is, this app is my default thing to play when I have five minutes to kill. Full marks.

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.

Simple to learn, stimulates problem-solving and pattern recognition similar to Sudoku, but without having to learn a bunch of esoteric techniques. Potentially more than one correct answer to a given puzzle results in "I figured it out!" instead of "I finally got the right answer." 4 of 5 stars because the user interface could be smoother/prettier; ad banners are unobtrusive but I would be willing to pay for a version with no ads.

What's new
