This is the Deluxe Edition of Linkage, a strategy board game for 2 players by Ethan Larson.
Linkage is played on a 7x7 board with the center square blacked out. There are 24 pieces, 6 of 4 different colors. Each piece is a domino covering exactly two cells of the board. Both players use exactly the same pieces. The starting player is called "More" and the other player is called "Fewer". The goals of the game are opposite for both players. The "Fewer" player wins a finished game if the number of distinct groups of cells of the same color is less than 12. Otherwise the "More" player wins.

The board is made of 8mm thick 'ice' acrylic, laser cut and engraved. It measures 30x30 cm. The tiles are made of laser-cut 6mm thick acrylic. The discs are 8mm thick. The full set weights around 2 kilograms.
