For kids Binairo

Binairo is a gentle way into logic for a child: only two symbols to place, and three rules that are easy to say out loud. The small 6 by 6 grids here keep it manageable, and because every puzzle is proved solvable by logic, a child can always reason the next cell.

Difficulty

Larger grids have more lines to balance. Every puzzle solves by logic, with no guessing.

6×6, 9 given cells. Fill the rest with 0s and 1s so no three repeat and every line is balanced.

Two pages: the puzzle and its completed grid. Every puzzle is proved to solve by logic alone, by the same engine as our KDP studio.

How to solve a binairo

A binairo, also called takuzu, is a grid of just two symbols, 0 and 1, filled by three simple rules.

The method

1Never three in a row. Two of the same number may sit together, but never three. Spot two, and the squares on either side must be the opposite.
2Balance every line. Each row and column ends with as many 0s as 1s. Once one symbol is used up in a line, the rest are the other.
3Keep every line unique. No two rows may match, and no two columns. Use that to settle a tie late in the solve.
4Work the forced squares first. Fill the squares the rules force, then look again. Each one you place opens the next.

The one rule: Fill the grid with 0s and 1s so no three alike touch, each line is balanced, and no two lines match.
What the answer page shows: The full solution is printed at the back.
How the grades differ: Larger grids give the rules more room to interact, so they ask for more steps.
Good for: Logic solvers who like sudoku but want something lighter on arithmetic.
