Spicy! Farkel

This is a newer, advanced Farkel. Instead of regular dice, included are "spicy" dice. Each of the six die has one side where the pips are red, and they alternate on each dice. When a red side is rolled it doubles your score. Plus this game's rules indicate that you play high stakes, where any dice left unrolled by a player, can be rolled by the next player, to add on to the original score.

How do I play Farkel? (Sorry, we couldn't find one just for spicy, but it gives you a good idea!)
