Beschreibung
A game inspired by the Four Colour Theorem in which four shapes in four colours are placed in a virtual grid according to four constraints. Players take turns to put pieces on the board, according to the following constraints:

Connected: after the first piece, each piece you play must touch at least one other piece orthogonally.
Different move: you may not play the same shape or colour that your opponent just played.
Not adjacent: you may not place a piece adjacent to a piece of the same shape or colour.
Virtual grid: you may not play so that the playing area exceeds 9 squares in any direction.


The last player able to place a piece wins.

The four shapes used are shown below. Each player receives 16 pieces, four of these in each of the four colors. A total of 32 tetromino pieces are needed.




Four won (along with Veletas) the BoardGameGeek Best Combinatorial 2-player Game of 2013 award.
