1. Money's out of your a/c as soon as you put SP bet on. So you'd need a/c to cover all bets if early placement is your goal.
2. Upper limit only can be selected.

I play with the Geeks Toy where you can play the game trying to get matched but if not successful your bet turns to SP bet (optional) at the jump.
