Skip the line in front if you are only playing games
You can purchase "Spurs" (their version of a token or credit) at several kiosks throughout the building for the same price as the front desk area. Even if you don't already have a game card, you can buy one right from the kiosk. The kiosks accept cash or cards. Even if you are doing more than games, you might want to walk by the front desk at first and look around to see exactly what you want to do before paying for it.
