The winner will receive 2 $5 chips of my choice.

If this ends up being a quick win, I'll have a bonus round for a small grab bag of goodies to include chips, matches, card keys and whatever else I can fit in the bag. If it's not a quick win, I'll sent it all to the first person with the correct submission.

** A quick win will be any correct submission within 1 hour **
