Topic: Pocket Card Jockey: Ride On!

Hi there, starting up a thread about Pocket Card Jockey in general,
but my specific question to start things off is:

How does the Tough difficulty unlock new cups? Do you just have to keep winning races with this difficulty set?

Been loving this game, has an addictive feedback loop and I'd say it's great value for how much it costs.
Pocket Card Jockey away!
