Ok, on the back of the card there is a siver scratch area. You get any kind of coin and rub it on the scratch area with the coin held vertically. The silver part will rub off and there is the number you need!
go to denver
i think a remake of Pokemon gold and silver
In Pokemon silver after you get the expn card you will get a Pokemon flute melody on the last line of your radio which you can use to awaken the sleeping snorlax blocking the way to the cave that leads to Pewter city

In the radio tower after you answer a quiz

Scratch is NOT a TM.
It opens a door to your life @(^-^)@
There's a silver rectangle on the back. Scratch that off, and there will be a code. Type that in, and you get what ever it gives you. Turn the card around and you will see a silver bar. Scratch that off with a penny (or fingernail) and you will see a code. Then go to www.FreeRealms and type in your user and pass. Go to redeem a code and type in your code on the starter card. Launch the game then BOOM there you go.
Catch a certain amount of Pokemon and defeat the elite four to change your card from copper to bronze to silver then gold.
