Also Known As:

Domino Logic, Domino Search

Like many puzzles featuring digits, no mathematical ability is required for this puzzle. The figures represent the dots on domino tiles. The objective is to identify a complete set of dominoes.

To begin, search for one domino (number pair) that is unique in the grid. Check the double numbers first (eg, 6 6) as they are easiest to spot. Once you have located a single domino, its precise position should enable you to place others. As the number of dominoes to be found is reduced, it becomes easier to spot the ones you need. The check-grid provides a useful tool to keep count of the dominoes you have found.


Draw in the lines to show where each of a standard set of dominoes has been placed in the square grid. Cross off each domino in the check-grid as you find it.
