Of Stone & Wood

Of Stone and Wood is a quick, light, 2-player strategy game that takes 5 minutes to learn and 5-10 minutes to play enabling a "best of 3" competition to be easily played at lunch. Players are moving their pieces, swapping for adjacent opposition or mercenary pieces, or jumping adjacent pieces in order to form a line of 5 of their pieces, but be careful because the swinging loyalty of the mercenaries makes them just as useful to your opponent as they are to you. —description from the designer
