| Even and Odd Binairo® 
The puzzle your readershave been waiting for!
 
We published our first Binairo® in the summer of 2009 in Belgium’s largest newspaper. 
When the puzzle disappeared from the newspaper in the autumn, we were besieged with angry e-mails. 
Puzzlers wanted their Binairo® back! 
Today, the puzzle has regained its place in the newspaper and it appears in different countries.  
 
At first sight, Binairo® looks like another derivative of the popular Sudoku puzzles. 
But that is not true! The only thing that Binairo® and Sudoku have in common is simple rules and an addictive effect on players.
Directions Even Binary puzzle 
1. Complete the grid with zeros and ones until there are just as many zeros and ones in every row and every column.  
2. No more than two of the same number can be next to or under each other. 
3. Rows or columns with exactly the same content are not allowed. 
 
There is only one valid solution per puzzle that can be reached through logic and clear thinking alone!
Directions Odd Binary puzzle 
The directions for the odd  puzzles are the same as those for the even  puzzles with the exception that each row and column must contain an extra one. 
E.g. the rows and colums of an odd 13x13 grid must contain 6 zeros en 7 ones.
