Printable Binario
Binario — some know it as binairo or takuzu — is a board of zeros and ones. Fill in the missing digits so that every row and every column holds as many of one as of the other, nowhere three alike stand side by side, and no two rows and no two columns are the same. A few digits are given at the start; the rest is the puzzle.
Every day there is a new board in each of three sizes, dealt to everybody alike and solvable without a single guess. Pick a size, print the sheet, and take it wherever a screen would not go — a pen is all it takes.

How to play
Fill every empty cell with a zero or a one so that each row and each column holds as many zeros as ones.
Never three alike side by side — not in a row, not in a column.
No two rows read the same, and no two columns do either.
Tap a cell for a zero, tap again for a one, once more to clear it. The digits the board came with stay put.
A reddish cell is one of three alike in a row, or a digit its row or column already has too many of; two lines that read the same are shaded too.
