Blokus (/ˈblɒkəs/ blowkus) is an abstract strategy board game for two to four players, invented by Bernard Tavitian and first released in 2000 by Sekkoïa, a French company. It has won several awards, including the Mensa Select award and the 2004 Teacher's Choice Award. In 2009, the game was sold to Mattel.
The game is played on a square board divided into 20 rows and 20 columns, for a total of 400 squares. There are a total of 89 game tiles, organized into 21 shapes in each of four colors: blue, yellow, red and green. The 21 shapes are based on free polyominoes of from one to five squares (one monomino, one domino, two trominoes/triominoes, five tetrominoes, and 12 pentominoes).
The standard rules of play for all variations of the game are as follows:
When a game ends, the score is based on the number of squares in each player's pieces on the board (e.g. a tetromino is worth 4 points). If a player played all of his or her pieces, he or she gets a bonus score of +20 points if the last piece played was a monomino, +15 points otherwise.
Blokus rules allow for two and three player games also. In two-player games, each player takes two colors. In three-player games, either one of the players takes two colors or else "the pieces of the fourth color are placed on the board in a non-strategic way."
Sekkoïa and its distributors manufacture four additional versions of the game.
Blokus Duo is for two players only, and uses a smaller (14×14) board; the piece colors are purple and orange. The two starting squares are placed, not in the corner (as in the original Blokus game) but nearer to the centre. This makes a crucial difference in the flavour of the game, because players' pieces may (and usually do) touch after the first move. Even more than with the original game, Blokus Duo is an offence-centred game; it is also a much purer strategy game than the four-player game, since one is not in danger of getting ganged up on by three other players (as sometimes happens with the four-player version).
