Milton Bradley (by way of Hasbro), 1967, 2 players, ages 7 and up. Another classic game that my son and I enjoy playing. I'm pretty sure it teaches some basic analytical thought processes to the neophyte gamer, but without delving into all that, it's still pretty fun to play after all these years. Apparently it's been around just about forever as a public domain pencil and paper game. The first known published versions appeared in the 30's. The present Milton Bradley version has been continuously in print since 1967. An electronic version was released in 1989 which is kind of cool, although a little limited in its implementation. It comes with a few dozen preset ship layouts that the players choose from and then place their ships to match before having at it. It would've been a lot cooler if the whole thing was wired and when you placed your "shooting" peg, it tried to make a connection to a ship and then gave you the resulting hit/miss announcement. Then again, I suppose that would've driven up the cost a tad. Anyway, it's all good.
