I just received an email about this recently and already there are 200 enrolled persons, and the limit is 500 so better hurry!
There will be a second round beginning in November, in case you miss out!
Enrollment is October 1 - 11 and promotion deadline to earn "Winvelopes" and reach the finish line is October 21
Get a "Winvelope" for texting each day AND every $2 wagered
If you get to the 21st space before the promotion is over, your prize is DOUBLED, you have to reach the 21st space by October 22
The prize "winvelopes" will be revealed AT Mystic Lake through October 22 - 29 and prizes must be redeemed through October 22 - 30
