Yeah, it's very addictive.
I used to play it with a friend, it was a tough duel, but then I found out that there's a way to cheat, so I lost interest interely.
By the way: casual games with cheats???
In any case, I've almost solved my issue: I've found a site with a friend-list integrated, so it's possible to show directly your score to friends.
It's not exactly what i needed but it's enough.
