Squish

Squish is an unification game with the theme of "condensation". Players take turns moving one of their pieces one space at a time toward an friendly piece on the same line. If a player's piece moves to a space occupied by an opponent's piece, it is captured by replacement. If there is no friendly piece on the same line, the piece cannot move. The first player to move all of the pieces on the board adjacent to each other or to prevent the opponent from moving wins the game. This game is included in Generic Board "Hexagonal". —description from the designer
