Details we figured out:
Have to remember during setup that markers start off the board, not on it.
You return a marker to start and take coins from the pot when it moves past the far end of the board, not to the final square.
At the end of the game, coin stacks belong to the player they're in front of. With stealing, it turns out that you may have coins from your opponent in your stack, and they won't all get cashed in before the game ends.
I'm thinking that 'Crossing' would be a good name...
