There is €1,000 in cash up for grabs for the one who gets the most new players from now till Tuesday midnight.
You and your new players will also be rewarded with 10 free tickets each for every new signup.
All new players need to verify their mobile numbers and that's all. See the competition leaderboard.
It all starts now, make sure you're there.
Good luck and happy sharing!
