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 a number of 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 exactly the same).

Each 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.
