The Blokus instructions refer to the corners that are unprotected and jut out the most as 'advanced' corners. Be proactive about surrounding your opponents' most available, advanced corners. Remember that while you can only touch the corners of your colored pieces, you can abut all sides of another player's piece.

Each of the 22 pieces is a different shape.There are: 1 piece with one triangle, 1 piece with two triangles, 1 piece with three triangles, 3 pieces with four triangles, 4 pieces with five triangles and 12 pieces with six triangles (see figure 1).Object of the GameEach player has to fit as many of his/her 22 pieces on the board as possible.Game PlayEach player chooses a color and places that set of 22 pieces in front of his/her side of the board. The order of play is as follows: blue, yellow, red, green.The first piece played by each player must cover one of the starting points indicated by the triangle symbol (see figure 2).Each new piece must touch at least one other piece of the same color but without contact between two sides (see figure 3).There are no restrictions on how many pieces of different colors may be in contact with each other.

Three colors may touch at the same intersection (see figure 4).Once a piece has been placed on the board, it cannot be moved during subsequent turns.End of the GameThe game ends for a player when he/she is blocked and can no longer put down any pieces or that player has run out of pieces.However, a player MUST play if it is possible to play.

Blokus (/ˈblɒkəs/BLOK-əs)^[1] is an abstract strategyboard game for two to four players, where players try to score points by occupying most of the board with pieces of their colour. It was invented by Bernard Tavitian^[2] 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.

Gameplay[edit]

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 84 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:^[3]

• Order of play is based on the color of pieces: blue, yellow, red, green.
• The first piece played of each color is placed in one of the board's four corners. Each new piece played must be placed so that it touches at least one piece of the same color, with only corner-to-corner contact allowed—edges cannot touch. However, edge-to-edge contact is allowed when two pieces of different color are involved.
• When a player cannot place a piece, he or she passes, and play continues as normal. The game ends when no one can place a piece.

When a game ends, the player with the highest score wins. 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). A player who played all of his or her pieces is awarded a +20 point bonus if the last piece played was a monomino, or a +15 point bonus for any other piece.^[3]

Two and three player variations[edit]

Blokus rules allow for two and three player games also.^[4] 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.'^[4]

Expansions and spinoffs[edit]

Sekkoïa and its distributors manufacture four additional versions of the game.

Blokus Duo/Travel Blokus[edit]

Atomic society youtube channel. 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).

Blokus Trigon[edit]

Blokus Trigon uses pieces made up of triangles rather than squares (polyiamonds), and is played on a hexagonal board, a version optimized for three players but can be played with 2, 3, or 4 players. The same rules apply, meaning that 2 edges cannot touch; however, as it is isometric, a corner touching an edge is allowed.

Blokus Giant[edit]

Blokus Giant is a larger version, with the game board being about 570 mm (22 in) square.

Blokus Junior[edit]

Blokus Junior is targeted at younger children. Like Blokus Duo, it is played by two players on a 14×14 board but it uses only a subset of the pieces that have a supposedly simpler shape. There are 12 unique pieces. Each player gets two of each kind, 24 in total. The game also comes with a set of sheets with single-player puzzles, which show positions in which the player needs to connect two pieces following standard Blokus rules.

Rumis/Blokus 3D[edit]

Blokus 3D, originally marketed in a Mayan theme as Rumis, uses pieces made up of unit cubes, in every permutation of three and four cubes in three dimensions. Stefan Kögl created Rumis independently from Bernard Tavitian, and is thus not related. However, Rumis was rebranded into Blokus 3D since the Blokus brand proved stronger than Rumis. There is also a major rule change; instead of being required to place pieces so they touch corner-to-corner, a piece must be placed such that it touches a face of another piece of the same color. Also, a player placing a piece cannot do so if it would create any empty space underneath any part of the piece. The object is to build one of four different structures, each with its own placement limitations: the Tower, Wall, Steps, and Pyramid. Players attempt to place their blocks such that at the end of the game, when the structure is viewed from above, their color has the most squares showing.

Video games[edit]

Funkitron developed a PC casual game version of Blokus called Blokus World Tour. Released in December 2007, Blokus World Tour was similar to the board game version of Blokus, but also featured 16 AI opponents, music and sound effects, and multiple game modes, including a tour mode, quick play, and Blokus Challenges.^[5]

For some time, there was an official online version of Blokus where visitors could play with opponents all over the world. Mattel suspended the online game on May 18, 2012, stating it did not meet its playability standards.^[6] It is now possible to play blokus online at Pentolla.com.^[7]

The PlayStation Portable has Blokus Portable: Steambot Championship, which features characters from Steambot ChroniclesWits and wagers questions. playing the Classic, Travel, and Duo versions of the game.

A Gameloft developed version of Blokus was released for iPhone, iPod touch, and iPad in April 2010, featuring the Classic and Duo versions of the game, local and online multiplayer gameplay, and single player tournament mode.^[8] A clone named Quadrus, is available since January 2014.^[9]

As of January 2014, the Gameloft version of Blokus is no longer available from the App Store. Currently, the officially licensed Blokus app is developed by Magmic, and is available for iPhone, iPod touch, and iPad. This version includes solo play and multiplayer options, integrating the user's Facebook and Game Center friends and allowing them to compete on a tournament leader-board.

There is also some open source software based on the same concept of polyominoes as blokus does, for example Blokish,^[10]Blockem,^[11] Freebloks^[12] or Pentobi^[13] for desktop and Freebloks^[14] or Blokish^[15] for Android smartphones.
