The object of the game is at the last turn to compare the symbol on the card remaining in the player's hand with the symbols on the player's case card. The player whose symbol has the most points is considered the winner. Another way to win is to be the only player left during the round, some cards allow this.
The game has mechanics similar to other pocket games like Love Letter and Lost Legacy. Players accustomed to this type of game will feel familiar with the rules. Not so experienced players will be able to quickly learn the rules of the game.
