been playing a lot of this game on my breaks, it's awesome. it's like a fast game of chess with no board and cool looking pieces that feel like dominoes.
here it is on amazon[link]
you can play at this site for free, as a guest or with an ID. you can play a comp or people around the world in real time. games are usually 10 to 15 minutes[link]
great book on amazon written by a guy that plays there, he's very nice all the folks on the site are very helpful.[link]
and a kinda longish video on youtube but helpful with rules etc. [link]
