Total Rewards NFL $1,000,000 promo
For every 50 tier credits you get a game piece. If you browse the promo you will see how many game pieces you've accumulated and how many boards you've filled--you need 8 boards for the MILLION. Based on what I see NORTH/SOUTH AFC/NFC are probably VERY rare. The promo is not well described.
But a MILLION $ is nice to think about.
