I've just installed a nice feature to the site where you can predict the upcoming games in the league.
You can bet on every match in Serie A each round. You get:
0 Points for a completely wrong bet
1 Points for a properly guessed match winner
2 Points for a correctly guessed match winner and goal difference (Winning team/Losing team)
3 Points for a exactly guessed match result
Additionally, you get up to date tables, cross tables (team vs team), team forms, kick-off times and of course a ranking system for everyone that participates.
If there's interest I could add more leagues in the future.
