A few observations
We noticed a few things while playing this that were unclear in the rules:
1. What happens if a player ends with suit chips for suits that only have an Ace, no other cards?
2. We often ended play with players having uneven amounts of suit chips. If you have players A, B, C, and D, and player B ends the round by placing the last card and taking a chip, players A and B have one more chip each than players C and D. Is this by design?
