Thanksgiving Sudoku is a picture sudoku for kids, with turkeys, pumpkins, apples and corn instead of numbers. Put one of each in every row, column and box, starting with small 4 by 4 grids that suit five-year-olds. A pumpkin pie and a pear join in on the bigger 6 by 6 boards. Play through an autumn garden, a pumpkin patch, an apple orchard, a harvest farm and a sunflower field under a smiling afternoon sun, and win a new board for every stage, from Cranberry and Maple to Falling leaves. Every puzzle has exactly one answer, found by thinking, never by guessing, and there is no timer, so children can take all the time they need. It is a calm way to build logic and careful looking, and Wombat is always there with a gentle hint.
