I need a challenge system like this (registration required):
http://challenge.atpworldtour.com/atp/user-bracket.php?EVENT=5& X=1336866465
How it works:
I ride the table of the tournament and users place their bets until the final phase. Who scores the most points wins the challenge.
To choose the winner the user should just click on the player’s name.
The system should generate a ranking (in module) renewable every 12 months.
