You don't have to play every day to participate in the Iron Man Challenge thing. It goes monthly, but you have different levels for different options. For instance:
points per day 50 100 200
15 days -- Bronze Silver
20 days bronze silver gold
25 days silver gold iron
Then you get the following Iron Man points per level at the end of the month:
Iron 100
Gold 70
Silver 40
Bronze 25
And if you reach any Iron Man level in the consecutive month, the amount of Iron Man Points you receive each month increases about 20% up to 300 per month for Iron Level and up to 60 per month for Bronze Level. And you also get into a special freeroll each month for reaching a level.
So, it's actually a great program. You get points just for playing, which means you are also building up for Full Tilt Points and your
rakeback. It's really a multi-layered all inclusive type promotion.
