This is a relatively easy to learn strategy game that can be played by printing off a hexgrid and using coins and/or similarly sized markers. It seems to be fairly unique, as I am not aware of any other games quite like it, and its game-play seems to be good enough to justify a little bit of set-up time. Beginners will want to use the base-4 hexgrid at first.

I am designing a board that would consist of indentations so that one could just use marbles as pieces and "pour" them onto the board to set it up.
