Wordfeud

Wordfeud is a multiplayer mobile word game developed by Håkon Bertheussen in 2010. Based on the principle of Scrabble, it allows players to play games with up to 30 friends and random opponents simultaneously. It received positive reviews from TechRadar and PCWorld.

By 2011, the game had nearly eight million users worldwide. In July 2020, Norwegian news site Dagens Næringsliv reported that the game had made Bertheussen a multimillionaire.

Reactions
The game sometimes requires so much attention that conversations are cut off and interrupted when a player makes a move. In September 2011, a café in Zwolle, the Netherlands, sought publicity by banning the game in the café.
