NXS

From BoardGameGeek:

NXS (pronounced "nexus") is an abstract strategy game played on hexagonal boards with hexagonal pieces. Each player has his or her own board. Each player sets up their pieces in either a short game (7 piece), medium (10 piece), or long game (13-14 piece) configuration. Players push their boards together in either a two or three player arrangement. Players alternately move their pieces (and rotate them) in an attempt to capture both enemy pieces, and enemy territory. Enemy territory is captured by "surrounding" it. Game play continues until one player captures a predetermined amount of enemy territory (usually 10 spaces). Notes: Although there are official short, medium, and long game setups, players can choose any agreed upon starting position of pieces that they like. The amount of territory required to win can be adjusted for different types of play. When playing advanced rules, a player may rotate his or her entire game board as a move. Although it is officially a 2-3 player game, 4 and 6 player games can also be played using an extra neutral board.
