Have you ever played Othello or Reversi? Well this is it's more fun, angular cousin. Formerly written back in the dark ages of 1992 by Argo Games, this version is an almost identical recreation, with all the funky graphics and wacky sound effects that made the original so addictive.

You play as the red diamonds, and your goal is to "take over the world", or at least the board, by leaping into spaces adjacent to those evil watery globule thingamabobs... trust me, it's easier to play than explain.
 

To Play the Game: 

Hexxagon is a straightforward mouse point-n-click game, but if you like to be awkard, you can use the tab key. 

Shift your little pieces around the board by selecting them, and then choosing your destination. Doubling and jumping moves are shown either by a green or yellow highlight.
