ok so wildcoins can earn me a discount of .25 per token. got that. But can i find where it might say how much credit i have toward a game?

If you go through the purchase process for a game, the second step (the first page after you have to log in, which will ask you for your billing information) should display the discount you have earned for this game. If you add several games to your shopping cart, you should be able to see your discounts for all the games at once.
