Hexxagon is a kind of Attaxx/Blobs in a hexagonal form.
The game is a distant relative of reversi.

Object: Capture all of your opponents pieces. You can drop a new piece on any position next to one of your pieces, or you can "jump" an existing piece by moving it two squares in any direction(s). All opposing pieces in the six squares adjacent to where your piece lands change color to become your pieces.

There are several different boards to play with, including boards with blocks you cannot move onto.

Try not to leave any holes in your positions, since they can be easily occupied, capturing many pieces. Jump moves are especially vulnerable to leaving dangerous holes. Early in the game, make drop moves and try to move towards the center.
