Echelon is a two or four-player board game with the goal of dominating the board by forcing all other pieces off the edge with superior row strength. Play against your friends online, against the computer, or play hotseat games offline. Check the Q&A within for details.
(Note, subscriptions are no longer required to play. Former subscribers do gain access to two additional playing boards, however.)
Requires BYOND 334 or later.
