About the game

Introduces 6 additional cards to the game: 1 Nebula card (red), and 5 Comet cards (gold) numbered 4-8. Nebula: The Nebula card is a very powerful card that can avoid taking tricks in most cases as it does not need to follow the "Must-Follow" rule and can be played at any time on your turn, regardless of the suits played by other players. It is then turned face down immediately. Comets: The initial impression of the Comet cards may be that they act similarly to but seem weaker than the Black cards. However, since there is no need to follow the "Must-Follow" rule after the Break, the Comet cards can be used to aggressively target "Collision" and avoid taking tricks.
