(Rules and example (1-6) from WPC 2015 IB)
History of the puzzle
Not ascertained. Probably German invention. Oldest example found is from 1996 German Nationals.
WPC 1994 had similar puzzle. There were no outside hints and for each domino whether they are placed horizontally or vertically were given.
Also known as "Domino Figure." The name is probably a translation of "Dominofigur" from 1996 German Nationals.
