PILEUP MODE is an alternate competitive way of playing Crashword where the object is to crash on purpose!
On each turn, clue-givers score a number of points equal to the number of players involved in their crash, e.g. if you and 3 other people typed the same clue, you would each get 4 points. So in order to win, you don't just want to crash, you want to crash on the most popularly written clues!
If the guesser guesses their word right, they score the same number of points as the clue-givers involved in the biggest crash.
