Wayne has a good point. I said the "game card" automatically appears after you bid. That is not true. While you do not have to register, you must first click a button that says "I want to win." Thereafter, for that day at least, the free "game card" will automatically appear after you bid -- up to five times a day.

To find that button, click this eBay link:

Here are the ebay game rules:

(Incidentally it appears to me that eBay is wrong when they say the button appears on their home page.)

Good luck.
