If you've got a bit of a competitive streak and are fed up with playing games against a CPU opponent all the time then you should give SPB Online Games a try.
SPB Online Games contains four different board games for playing against other people online: English Checkers, Russian Checkers, Hexagon, and Reversi. All of these games are selectable with a single-click from the well-presented front screen. This screen also lets you create a user profile by clicking on the 'My Profile' icon. Here you can select from a range of pre-installed avatars and enter a nickname. Unfortunately, that's as far as the social profiling goes, but it would've been nice to have had some more options for personalizing your SSPB Online Games games experience.
The games themselves are fun and easy to play. You just click on the game you want to play and within a few seconds you'll be connected to another player. If you've never played any of the games before then don't worry, because each has detailed instructions available, and you can choose from three difficulty levels.
Playing against other users is great fun and somehow makes SPB Online Games more exciting than most Pocket PC games. I also liked the fact that you can talk mid-game with other players through a straightforward chat interface. Unfortunately, it seems like there aren't always 'real' human opponents available and often you'll end up playing against a bot, which kind-of defeats the object really.
I guess the only question you need to ask yourself before you install SPB Online Games is if you really want to incur Internet costs just to play a mobile game.
If you have a flat-rate data plan though, I would definitely recommend SPB Online Games as a fun way to pass some time and make new friends.
