Ahh, okay. Thanks for the explanation. That was not how we interpreted the rules, but that makes a lot more sense. So instead of working on one molecule at a time, you really want to get all 3 correct before making the guess.
Great feedback and thanks for posting. Yes, you want to use a guess token when you think that many of your builders are correct, not just one. When you use the guess token, the knower will signal "yes" or "no" to each individual builder. And then your whole team is much closer to winning, AND you receive 1 clue token back for EACH builder that is correct. So if all three builders are correct when you submit the guess token, the knower will flip all three secret molecule cards for each player that was correct, AND THEN put 3 clue tokens back into the pile of available clue tokens. Hope that helps!
