Snails 1.9b2 and above (the current beta is 3) supports network-based multiplayer. It can be played online via the Internet, but does not get along well with NAT or firewalls. If you want to play over the 'net, you must connect your Pocket PC
directly to your Internet connection, whatever that may be. Hopefully future versions will work from behind a router. If you play against someone on your local network, however, it's great fun, and highly recommended! (If you've ever played "Worms," Snails is the same type of game.)
