The listing for this game says 1-2 players, but I see no mention of anyone playing it solo anywhere. Are there actual solitaire rules, or is this that "you-can-play-both-sides-so-it's-solitaire" garbage?
The other three DC games here on BGG are listed as 2 player. Don't know why this one is listed as 1-2 as that's not the case.
Seems like one person has given it a rating for 1 player so maybe that's why but the game is meant for 2 players.
EDIT: I've requested a change to the front page of CoU to reflect that the game should have a minimum of two players. It will no doubt take a little while before the update goes through.
