In Mon Protocol, players take turns playing cards in numerical order, fighting to receive the points of the cards in play. It's important to respect the order as much as possible, or other players might steal your points! At the end of the game, the player with the most points will be the winner.

The game proceeds with players taking turns, starting with the first player. On their turn, each player must play, change or discard a card. When done, the turn passes to the next player on the left. This proceeds until the game is over.

The game ends when someone runs out of cards and the game has gone one round from there. The player with the highest score wins the game.
