Mascarade
Mascarade is a 2013 card game by French game designer Bruno Faidutti.
Each player starts with 6 coins, and is dealt a character (initially face up, but concealed during game play). In each turn a player has three possible actions: to look at their character, to swap (or not) their character with another player, or to announce their character. When doing a swap, the player puts both cards under the table, face down, then returns them without saying which is which. When they announce a character, if unchallenged, they can perform the power associated with that character; if one or more other players also claims to be that character, then all involved players reveal their character, the true one (if any) uses the power, and then all false ones pay a coin to the courthouse as a fine. The first player to get 13 coins (or the richest player when somebody goes bankrupt) is the winner.
