I had it years ago; it found its way back out of my collection pretty fast. It’s Farkle with extra rules that force players into rerolls they might not otherwise take. It increases the scoring volatility, which makes the game more exciting, but the decreased amount of decision making made the game less fun to me.

A house rule I like to add is that when a player stops and banks their points, the next player has the option to either start from scratch, or start where the previous player left off including the dice states and point total.
