I hope it's not Reversi! That's way too easy for computers and fun for people will be gone soon!
btw, I do not see any problems in introducing a wordgame-bot to this site. It's a great chance to practise the game against a 'strong' player. As long as it's beatable or as long as you understand why you are beaten, any bots are welcome :-)
I agree, Reversi computers will be far to good for us mortal humans. I'd welcome anyone who tries to make a HEX-program, though! I've been playing with the thought myself, but so far I've not found the time. I've tried playing against a program called "Hexy" on the internet, but that game is not as good as a good human player. Also, I've been told that making a good "GO" algorithem is supposed to be very difficult, but what would I know, I don't play GO...
There are a couple other programs that play hex also. Queenbee plays on an 11x11 board, but it's even weaker than Hexy. There is also a new open source program, Six, which beat Hext, but I haven't played it. If you were interested, you could probably modify it to play 13x13 fairly easily.
