Personal Aims

  1. Add a “game” element.
  2. A complete game flow.

Main Content

This game is made up of 18 cards in four colors, each with 5 “rock, paper, scissors” cards, plus 3 “spades” cards. 

Each card has the same shape and pattern on the back, except for the logo on the front. 

Basic Rules

A game consists of three players and a deck of cards.

At the beginning, rock, paper and scissors are shuffled together and randomly distributed to 3 players. The remaining cards are stacked aside after shuffling as a common deck.

The whole game is made up of several rounds, each of which consists of “bid”, “play” and “settlement”. The winning player of each round can choose a card from his hand to put at the bottom of the common deck, the losing player needs to draw a card from the top of the common deck, and the tie does not change.

The game ends when a player’s hand is exhausted or the deck is exhausted, and the player with the fewest cards at the end wins.

Bid phase

Any designated a player to start, by the player first “bid”, called the player as “dealer”, then according to the clockwise/counterclockwise turn. “Bid” means that the player draws the card at the top of the pile, examines its color, then places it back up next to the pile and says the color of the card he wants to play. In particular, you must tell the truth when you draw spades, and you can lie the rest of the time.

Play phase

After the call, the player will select a hand and play it back up.

(Spades cannot be played)

Settlement phase

After all the players have played a card, everyone shows the color they played.

There is a mutual restraint between the colors: rock over scissors, scissors over paper, and paper over stone.

For “dealer” :

If at least one player’s card is restrained by declarer’s card, declarer wins the round; If no player’s card is restrained by declarer’s card, declarer loses. Otherwise, it’s a draw.

For non-dealer players:

If the color is restrained by the declarer’s color, the round fails and a card needs to be drawn from the public pile into the hand. If the color is the same, the draw is called and the card is withdrawn from the hand.

Critical Reflections

1. The original idea was to add elements of “cheating” and “game” to the game. At first, I wanted to design the game by “matching card colors to each other”, but I found that way of playing was not suitable.

2.Then I tried the idea of “mutual restraint of card colors”, using the most basic restraint logic of rock, paper, scissors, and found that the game became more competitive and gaming.

One problem that bothered me was that while the logic of rock-paper-scissors wasn’t complicated, it wasn’t easy for players to guess each other’s card colors and lie about their own. But because of “can only use 18 cards to make a game” restrictions exist, how to reasonable distribution of various design and the number of different colors’ cards to the rationality of the game and the interest maximization has become a difficult problem, in addition this prototype undoubtedly also needs way more tests to end the game process the possibility of a variety of results, to ensure that the game will not have a logical error in the process.
