You can always check on your account how many credits you have (log in and click on FUNPASS). Redeeming is very easy:
When you’ve found a game you want, click on the ‘Or buy the game for _ or 1 Credit »’ link that is displayed below the big red/brown download button on the game page. If you’re not logged in yet, log in to your FunPass account. Your credit will automatically appear in your Shopping Cart and the price will change to 0.
Boom, an extra game in your account without additional costs! 🙂
