Katamino Pocket

The game consists of 12 different pieces built with blocks at right angles, so each piece is made up of 5 "squares". (Think Tetris pieces, but 5 squares instead of 4.)

An old version of the game had only 10 pieces; the completely straight 5 square and the 5 square "plus sign" were not included. Both versions also have plenty of 1 or 2 square "filler" pieces.

The game board is built with a movable divider so one can take sets of 4 up to the full set of 12 pieces and form a rectangle of 5 blocks by X. (Where X = the number of wooden blocks as a whole).

The two or three player strategy game is played on a square board divided into 64 smaller squares. Players take turns placing a piece on the board. The first player who can no longer place a piece loses. (Similar to Blokus )

Two player puzzle gameplay is achieved by dividing the board into two sections, each player choosing five blocks and also receiving 4 small "filler" blocks of 1 and 2 squares. The first to fit all of their blocks perfectly on their half of the rectangular board wins.
