Twin Sudokus*

Number Puzzles

This is a twin variation of Sudoku on two "standard" 9x9 grids which are solving simultaneously using all rules as in a "standard" Sudoku.

The object is to fill in both 9x9 grids with nine different elements (nine different pics in the top grid, and nine numbers 1 through 9, in the bottom one) so that each row, each column, and each of the nine 3x3 squares (outlined with the bold lines) contains all the nine different pics in the first grid, and nine different numbers 1 through 9 in the second grid.

The main trick of this puzzle is that, in fact, we have the same final composition of elements for each grid, but in one of them numbers are substituted with pics, each number with its own pic. The start positions of elements are different, and so the grids supplement and help each other while you solve the puzzle.

To solve the puzzle you can print the above grids. For this, click the image of the grids to go to a new window with these grids; then you can print them.

Merry Christmas!
