I've been doing fantasy sports since 1998 on Yahoo and just started playing daily fantasy in the past year. I do FanDuel and DraftKings, but I actually kind of like Skyllzone a little better. When they started earlier this year with basketball I did it for a couple weeks and ended up winning $50 total. If you play fantasy sports, they are unique in that you are playing 9 computer opponents in each contest and there is no cost. For football you can have five drafts/contests (they use a snake draft) per week and you win points depending on where you place. They also have cash games (1000 points to enter) where if you place first or second you win $15 and $5 respectively. Like I said, entry to cash contests is through points, but so far each week they have given me an additional 2000 free points anyway.
One other, potentially large bonus, is they are having a $100K tournament in Week 15 of the NFL. Again, there is no cost to enter. You earn entries (up to seven) by virtue of winning one of your contests. I had a lucky first week and won three entries. Not as lucky since.
Anyway, this weekend they are having a promo where you will receive 2000 points (good for two cash entries) when you join and use a code I can send you.
Again, there is no cost to join anything. I'm assuming they are running this football year free to get any kinks out before charging something down the road. But it is free now and fun. Plus a draft only takes a couple minutes.
So if you are interested, or have any questions, shoot me a PM or ask below.
