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 very good, but filling in all the blank cells is tedious and could cause repetitive stress injury. Please add a feature to fill all blank cells (like in your suguru app) and/or fill cells by swiping the numbers rather than tapping each number individually. On a 9x9 puzzle filling in 81 cells by tapping each individual number is ridiculous. Thank you.

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.

Really fun puzzles! No ads. What's not to love? I would recommend a setting where if you press and hold a button, it clears all the other selections. For example if I know a cell is a 3, but I had "1, 2, 3, 5, 6, 7" penciled in, it's a little annoying to unselect all the others.

What's new
