Create a network of machinery and plants in order to save a bizarre world! Two players collect tiles and create their own machines.
To retrieve a tile, first, you need to put it on your side of the Registry, a common market for both players. But to add a tile to your network, you need to release it from the Registry, by putting a new tile in play... Ideally, by doing so, you can also prevent the opponent from getting new tiles... or force them to take a tile at an inopportune time!
