Roll or Bust (also known as "Pasch & Crash") is a fast party game for several players: collect points with one die – but roll a 1 and the whole turn is gone.
Whoever reaches a set target score first wins. You collect points turn by turn by rolling repeatedly and adding up the pips.
Roll as many times as you like and add up the pips. After every roll you can lock in the points collected so far (banking them to your score) and end the turn – or keep rolling for more, at your own risk.
If you roll a 1 before locking in, all points collected during that turn are lost and it's the next player's turn. That's the whole appeal of the game: keep rolling for more points, or stop in time.
