you have to unlock all the character cards of a level and you get the bonus game. the more levels where you unlock all the cards, the more traks you have to play on.
The code is spongestar, but you have to get all twelve bonus cards to unlock the secret character
You have to add the cards of the books and card packs. Card combos unlock clues. Complete the missions to unlock more clues. When you have all the card combos complete and you have played all missions you will have all the 39 clues. Don't use the replicator cards if not necessary. Use them when you need to unlock a card when it has not been unlocked even after you have added all the cards of the books and card pack.

I think I've heard it's spongestar but you have to have 12 bonus cards to enter it in. I've also heard that I think it depends on how much money you have and how long you have played to get them.
