what is jumbo game membership?

what is jumbo game membership include we are trying to download wonder pets save the puppy and on my purchase history it says the jumbo game membership we have already purchased this game how can we play it?

Down load the game again and if needed use the code you received in your email.
when it says: Activated, you're alright.

Welcome to the pond! If your purchase history says "jumbo game membership" that means that you have committed to buying 12 games (or game credits) sometime in the next 12 months, and that you will get one new game credit each month for $6.99, and also that any game you buy will only cost you $6.99.

So... download the game in any fashion you like. If you have already purchased it, then after it is downloaded click "buy" and then "already purchased".

If you haven't already purchased and WANT to, and you have a game club credit, click "buy" and then "use a credit". If you don't have any credits, click "buy" and then "purchase".
