How to play Dominosa

A full set of dominoes has been shuffled into a grid. Put them back together.

The rules

  1. Join neighbouring squares, across or down, into dominoes.
  2. Every domino in the set appears exactly once. A set up to 3 has 0-0, 0-1, 0-2, 0-3, 1-1 and so on.
  3. So no pair of numbers may be joined twice anywhere on the board.

A quick example

1 and 2 join, and 0 and 0 join. Each pair is used only once.

Tips

Most puzzles take 5 to 15 minutes.
