Duplicate Scrabble was invented by Hippolyte Wouters circa 1970,5 a Belgian lawyer who spoke French as his first language. In 1972 he organised and participated the first French World Scrabble Championships in Cannes. Although only 8 players participated in this tournament, a World Championship has been organised every year since 1972 in a different city in several different countries, most recently in Tours, France, where 274 people participated.6
Due to the nature of duplicate, there is almost no limit to the number of players who can participate in a single game, and at the biggest international festivals, some games are played by more than 1000 people simultaneously. In French, duplicate is practised in France, Belgium, Canada, Switzerland, Senegal, Benin, Tunisia, Lebanon and many other countries.7
Duplicate Scrabble has been part of the Romanian national championship since 1981.
The rules of duplicate Scrabble can vary between different languages and different associations. Some of the general principles of duplicate are8
