What are binary puzzles?
A binary puzzle is a logic puzzle in which numbers should be placed in boxes. Most grids consist of 10x10 boxes, but there are also 6x6, 8x8, 12x12 and 14x14 grids. The aim is to fill a grid with ones and zeros. In a given puzzle are already some boxes filled. You must fill in the remaining boxes which must respect the following rules:

RULES
1. Each box should contain a "1" or a "0".
2. No more than two similar numbers next to each other in a row.
3. Each row should contain an equal number of zeros and ones (14x14 grids at each row/column 7 ones and 7 zeros).
4. Each row and each column is unique (No two rows and columns are the same).

Every binary puzzle has only one correct solution, this solution can always be found without gambling!

The first click on the empty field sets the field to "0", a second click to "1", a third click empties the field.

Simple rules but hours of puzzle fun.

TIPS
Find duos (2 same numbers)
Because no more than two of the same digits may be next to or placed under each other, duos can be complemented by the other digit.

Avoid trios (3 same numbers)
If two cells contain the same figure with an empty cell in between, this empty cell can be filled in with the other digit.

Fill rows and columns
Each row and each column has the same number of zeroes and ones. If the maximum number of zeroes has been reached in a row or column it can be filled in a one in the other cells, and vice versa.

Eliminate other impossible combinations
Make sure that certain combinations may or may not be possible in rows or columns.

Good binary puzzles are hard to come by and this one was pretty awesome. There are great options to choose from. You can play 6x6 thru 14x14 squares. Choose difficulty between 1 and 4. My only recommendation for the developers is to create a button to click to place 1s or 0s, rather than tapping once for 0 and twice for . it's more time consuming and leaves room for more mistakes

I generally like the app. My only complaint is that the app unnecessarily forces itself into full screen mode, which hides the navigation panel (home, back, and recent buttons. Every time I swipe from the bottom to show the navigation panel it triggers the "show solution" button even though I didn't press anywhere close to it.

I paid for No Ads. The charge came out of my account, the app updated to reflect the purchase for a couple hours and then Ads started back up. There's no contact method in the app. I had to go through socials and the message from had an option to attach screenshots that also didn't work. Very disappointed.
