Asterismo

Asterismo is a solo/cooperative abstract game up to 3 players, played on an hexagonal board. 63 colored (blue, yellow and red) disc-shaped pieces are randomly put on the board, forming a compact tree. A piece is "safe" if is connected to at least 2 pieces of the same color, or to at least 3 pieces. The goal for each player is to collect several pieces (in a 3 players game, 10 of a given color; in a 2 players game, 5 pieces of each color; in a solo game, 10 pieces of each color), while keeping every other piece safe. —description from the designer
