Duplicate Scrabble is a variant of the board game Scrabble where all the players are faced with the same board and letters at the same time and must play the highest scoring word they can find. Although duplicate is rarely played at competition level in English, it is the most popular form of the game in French and is also played in other languages, such as Romanian and Dutch. The largest French Scrabble festivals can attract over 2000 people and some individual tournaments can count over 1000 participants per game. Although not popular for competitions in English, the computer game Scrabble 2005 contains a duplicate version allowing up to 16 players to play on the same board at once. It was also used on the UK TV game show TV Scrabble as one of the rounds.
Duplicate Scrabble was invented by Hippolyte Wouters circa 1970, a Belgian lawyer who spoke French as his first language. In 1972 he organised and participated the first French World Scrabble Championships in Cannes, France. 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.
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.
