### Missing Constraints




 [ ] Symbol(■)  Draw One Card


 [ ] Symbol  Second card face up


 [ ] Symbol  Second card face down


 [x] Symbol (■)  Draw One Card


 [ ] Symbol (**=**)  Second card face up


 [ ] Symbol (≂)  Second card face down


 [ ] Symbol (✠)  Simultaneous play


 [ ] Since the model misses out on the turndynamics, and treats symbols as global counters (instead of being attached to specific cards), there are some additional constraints that will be required. Without these, I'm expecting to see the same card being used for multiple symbols. Some sort of **Symbol counter** per round that keeps track of total number of cards you've claimed for symbols would be a better approach.


 [ ] **Additional Card Play**. Every round, all players can opt to play one extra card per artist they've already played. Note that this rule is very ambigously worded in the rules. I'm planning to implement the "blessed" variant. See https://boardgamegeek.com/thread/473713/playingadditionalcardsduringscoring for more details.


 [ ] In case `DrawOne` card is the last card of a round, then `PlayableCards` for that round does not increase by 1, but only for the subsequent rounds. Since I'm maintaining awards as a boolean on the (Round,Artist) tuple, this becomes quite hard to model. Unless this gets violated in the winning entries, I don't plan to model this.
