In a Domino puzzle, you do not need to place any numbers, because they are already in the grid. All you have to do is draw outlines to create domino tiles containing 2 adjacent numbers. No diagonal connections are allowed.
The rule for Domino puzzles is very simple:
Complete the grid by in such a way that it contains all domino tiles with values 0-0 though 9-9 (*).
Tiles cannot be duplicated.
Here is the first domino puzzle. It is relatively easy, but not a complete walkover:
