Picture Sudoku

Every row and every column needs each animal once. Tap an empty square, then the animal that belongs there: a 3 by 3 with one empty square, then three, then four; then a 4 by 4.

Builds: Logic, holding two rules in mind

Words: cat, dog, duck, pig, row, column

Try it together: Set the table as a puzzle: each place gets a cup, a plate, and a spoon, never two of the same in a row.
