CHALLENGE #6: INSPIRED BY ANOTHER BOARD/CARD GAME This has a rare interaction with Trade Route that I'll try and address here. If there are any Victory Kingdom card piles like Gardens or Nobles, it is possible to take the Coin token there that is meant for the Trade Route Mat.
In this example I will use Gardens, but this applies to all Kingdom Victory cards. If no Gardens have be gained that game and the number of Panda cards you have in play is more or equal to the number of Coin tokens on the Gardens pile (3+ Panda cards and 3 Coin tokens usually), if you gain a Gardens, two things attempt to happen. (1) A Coin token gets moved to the Trade Route Mat and (2) you take 3 Coin tokens from the pile. Being that there are only 3 Coin tokens and you are trying to do things with 4 Coin tokens, one of these things doesn't happen. As they all happen at once, you do get to choose however. You could take all 3 Coin tokens, or only take 2 and put 1 on the Trade Route Mat.
Just know, once that original Coin token placed by the Trade Route setup is removed, the Trade Route Mat will permanently be down 1 Coin token. Adding more Coin tokens later to the Garden pile with Gardener and gaining a Gardens will not attempt to move a Coin token to the Trade Route mat, since it only cared about the original Coin token it placed, not just any Coin token.
If you do take the Coin token placed by Trade Route, it can be used normally like any other Coin token.
These cards are inspired by the wildly fun game:
