Must like Club Tyson on Facebook, then on the left go to the Back to School Prize tab, then click play, wait for the Prize Wheel to load, which if you have problems getting it to load there is a tab at the top that says " Having trouble with the prize wheel? Let us know" and you can report the problem. You will receive 1 free spin a day. Ends September 15'th 2011.
There are different levels of prizes to win from and I am not sure how to go up a level, the page will not load for me.
Bronze Level: Pig Eraser, Pencil Sharpener with built in Eraser, Chicken Eraser
Silver Level: School Supply Kit, Flip Top Lid Water Bottle
Gold Level: Stainless Steel Water Bottle, Soft Cooler Lunch Box
Platinum Level: HP Mini Netbook
