In the scoring section it says that Stoke Tokens are worth 1 point. Do you discard the Stoke Tokens when you score them? If so, I assume that scoring them is not mandatory? Also, can you score a Stoke Token you picked up on a previous wave?
Stoke tokens only add to your score if you use them while riding a wave. They can be used to adjust the power of a wave plus or minus 1 per stoke token used. All stoke tokens used in this way are discarded after scoring. Also keep in mind the cards which you adjusted using the stoke tokens are still scored with their printed power value (NOT whatever the adjusted value was).
