Sekkoïa and its distributors manufacture four additional variants of the game.
Blokus Duo Blokus Duo is for two players only, and uses a smaller board (14 × 14); the pieces are opaque with black and white colors (originally translucent with purple and orange colors). The two starting squares are not placed in corners (as in the original
Blokus game), but nearer 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 the original game,
Blokus Duo is an offense-centred game; it is also considered a purer strategy game than the four-player version, since one can't be targeted by two or more players at once.
Blokus Duo was among the five nominees for the 2006 International Gamers Award, General Strategy, 2-Player Category, and has won a ''Sceau d'excellence Option consommateurs (Protégez-vous) 2006'' — "2006 Consumers Option (Protect Yourself) Seal of Excellence".
Blokus Trigon In
Blokus Trigon, the pieces are
polyiamonds: made up of
equilateral triangles, and the board is hexagonal with a
regular triangular grid. This particular spinoff is optimized for three players but can be played by two to four players. The same rules apply, meaning that pieces of the same color are still not allowed to touch each other's edges; however, since the grid is
isometric, a corner touching an edge is allowed.
Blokus Trigon has won the 2006 Major Fun Award.
Blokus Giant/XL Blokus Giant is a larger version, with the game board being about square. It was later re-released by Mattel as
Blokus XL.
Blokus Junior 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 simpler shapes. There are 12 unique pieces. Each player gets two of each kind, 24 in total. The game also comes with a set of single-player puzzle sheets, each containing a preset piece position on the board and a set of pieces to place into the board following standard
Blokus rules.
Travel Blokus/Blokus To Go! Travel Blokus was released as the smaller version of
Blokus Duo, then re-released as
Blokus To Go! with pieces that could be snapped into the board for storage.
Travel Blokus was later re-released as the smaller version of the original
Blokus game, rather than
Blokus Duo.
Blokus 3D Blokus 3D was originally marketed in a Mayan theme as
Rumis, created by Stefan Kögl, independently from Bernard Tavitian. However,
Rumis was rebranded into
Blokus 3D because the
Blokus brand proved stronger than
Rumis. In
Blokus 3D, exactly like in
Rumis, but unlike in
Blokus "2D": • The pieces are four times the eleven possible
polycubes of two, three, and four (unit) cubes. • A piece must be placed such that it touches another piece of the same color by at least one unit
square, instead of
corner. Also, a piece cannot be placed such that it creates any empty space underneath any part of it. • Together, the players build (almost) one of four different ideal structures: the Tower, Wall, Steps, and Pyramid. Each structure has its own placement limitations. • Each player aims at having as many unit squares of their color on the
top of the stack and placing as many of their pieces as possible. At the end of the game, the player with the most squares from the
top view and the least remaining pieces wins.
Blokus 3D has won the 2008 Japan Boardgame Prize U-more Award. ==Video games==
