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.

I really love this app. There are many puzzles to choose from, and you can even pick what size board you would like to play! I also really like how the “notes” feature works—put in numbers into a cell, and if it’s more than one number, the app knows that you want to take “notes” on possible solutions. The only downside—which isn’t too big of a deal—is that you can’t turn off the “hints” or the advertisements. As for the hints, if you place an incorrect number in a cell when you have already solved the cells around said cell, it automatically highlights the error. My play style is to throw in numbers first and then reduce the amount of numbers in a cell, so it’s a bit annoying that I can’t turn off the hints; it would be great to have an “options” menu with the choices to remove hints and to remove ads (for a paid fee, of course). But, other than those two points, I love everything else about the game! It’s really fun. :)
The glitch seems to have been addressed.
I have played through all of the level 9 puzzles, and am working my way back through them again. The glitch mentioned on Sept 8 (maybe last year?) was gone as of today, 24 Nov. ‘19.
A session each day with these challenging puzzles has greatly helped my mental acuity as I continue to struggle with brain fog and the humiliating forgetfulness natural to aging. I particularly enjoy this app over others for two reasons: we are given enough space to jot notes on all possible numbers instead of being limited to only five possibilities; and while otherwise nice logic puzzle apps have a small number of a variety of puzzle types, this app focuses on Kropki only. My favorite type.
Fun puzzles, glitchy saving
This app works perfectly on my iPhone, however any night I open it on my iPad, it has cleared all of my progress and notes! So fun to play, but don’t get too attached to moving through the levels unless you want to screenshot your board any time you take a break.
