Ubongo is a board game developed by Polish-born Swedish game designer Grzegorz Rejchtman. It originally appeared as Pyramidens Portar by the Swedish publisher Kärnan and won the Swedish Årets spel prize in 2003. The game was later released in Germany in 2005 as Ubongo by the publisher Kosmos and got 4th place at the German board game competition and was among the finalists in the International Gamers Award.
The game is for 2 to 4 players of ages 8 and above, and takes about 20 to 30 minutes. Ubongo is an abstract puzzle game, based on a pentamino variant, reminiscent of a combination of Tangram and Tetris. The game includes a simplified version with fewer pieces, for children and beginners.
Ubongo is well suited for a game for the whole family, because its mechanics entertain both children and adults. Solving puzzles is entertaining by itself and provides excitement when combined with competition with other players.
The word "ubongo" means "brain" in Swahili, a language currently spoken in Eastern and Central Africa.
