Divide the grid into a given set of dominoes. Each domino should be used exactly once. The orientation of the letters does not matter. Empty cells are not part of a domino.

(Rules and example (using full set from 0-0 to 3-3) from PGP IB)

Rule variations[edit]

  • Oriented Dominoes: Present in WPC 2000. Numbers are represented by dots as in classic domino. Orientation of the dots mhas to be taken into account.
  • In WPC 2012/Round 1, some numbers were blanked out and solvers had to reconstruct these numbers too.

History of the puzzle[edit]

The puzzle was patented in 1893 by Richard Osa (Germany), under the name "Dominosa Omnibus".[1]
