Picture sudoku and no-repeat squares.

Fill small grids with familiar objects instead of numbers. The 4×4 boards follow picture sudoku rules with 2×2 boxes; the 3×3 boards are Latin squares with row-and-column rules only.

How to play picture sudoku & latin squares

  1. Select an empty square, then choose an object from the palette. Pieces marked with a lock are starting clues and stay in place.
  2. Place each object exactly once in every row and column. On a 4×4 board, every outlined 2×2 box must also contain one of each object.
  3. Compare the remaining possibilities until the board is full. Use Clear, Undo or Hint whenever you need to rethink a square.

Look for the missing object

If a row needs an apple, lemon and bowl, and already contains an apple and a lemon, the remaining square needs a bowl. Then check that column for another deduction. On a 4×4 board, use the outlined boxes as a third set of clues.

Before your next puzzle

Are the 3×3 boards sudoku?

They are Latin squares: each object appears once per row and column, without smaller boxes. The 4×4 boards add 2×2 boxes and follow the rules of a small picture sudoku.

Do the colors matter?

No. Every object has a written name and a distinct shape. Follow the names and positions; you do not have to tell similar colors apart to solve a board.
