Navigation without a stack

Hi all,

The app I am doing doesn't have a concept of "going back" in the flow of pages. It's a quiz game app, you start the game, go through ~30 pages and can then choose to start over again or go back to the main menu.

Any input on how to do this? At the moment I am using PushModalAsync - but that builds a stack, right? It seems unnecessary and smells of problems.

Thanks,
