Nexos is a board game similar to Blokus. The board is a rectangular 13×13 line grid. Each color uses 24 pieces that consist of up to four connected line segments.
The 24 pieces
Each color has a starting intersection on the intersection of the third lines close to a corner. The first piece must touch the starting intersection.
The board for Nexos with the starting intersections marked with colored dots
The following pieces must be placed on empty line segments such that a segment of the new piece touches an intersection that is already touched by a segment of the same color. It does not matter if pieces of other colors touch or cover the same intersection. However, pieces may not overlap. The junctions between the segments within a piece are such that two rectangular junctions of different pieces can cover the same intersection without overlapping, but straight junctions cannot.

The score of a color is the number of line segments on the board covered by the color, plus a bonus of 10 points if the color could place all of its pieces.
