If you log into your BetJam account, you should see a $10 credit. Mine was there a few days ago. Bought two $5 squares and the card was filled out and closed today. Drew 7/1 on one and 9/2 on the other. They started another $5 card or the $10 HIGH ROLLER card is still going. LOL
I'm assuming this was how it worked for lack of better instructions...
