Weft

Weft is a drawless connection game for two players: Red and Blue. It is played with trapezium-shaped pieces on the spaces (cells) of an initially empty basket-weave grid (board). The top and bottom edges of the board are colored red; the left and right edges are colored blue. All pieces are the same shape and only differ in color. They can be placed with any side (front or back) up. A cell can accommodate two pieces, and no piece can be placed in a way that makes this physically impossible. Play Red plays first, then turns alternate. On your turn, place a piece of your color on an empty cell. After your placement, for any two point-adjacent, like-colored pieces there must be at least one like-colored piece edge-adjacent to both. Two pieces are point adjacent if they share nothing more than a vertex, and edge adjacent if they share at least part of a side longer than a vertex. You win if there is a chain of edge-adjacent pieces of your color touching the two opposite board edges of your color. To make the game fair, Blue will have the option, on their first turn only, to swap sides with Red instead of making a regular move.
