I think most of us know this game, so it doesn't need much introduction, but I'll also give the rules for those who don't know. What makes this version of the game different from the others? It fits in your pocket and is no bigger than two credit cards.

Print all the parts and use a cutter to cut pins from filament in any color you want. You will need white and black for the clues.
The player who chooses a secret combination of five colored pieces covers his combination with a sliding cover.


Aim of the game: The aim of the codebreaker is clear: crack the secret color combination created by the codemaster. You have a limited number of attempts to do this. If you don't manage to guess the combination in time, the codemaster wins.

Preparation: The code master chooses four tiles and places them face down. The codebreaker now places his first guess by placing four tiles in one of the rows of the game board.

Scoring the tips: After each tip, the code breaker gives hints: A black marker indicates that a color is in the correct position, while a white marker means that the color is correct but in the wrong position. No mark means that none of the colors are correct.

Further attempts: Now the codebreaker uses these hints to determine the correct combination step by step. Each hint brings him closer to the solution, provided he interprets the clues correctly.

End of the game: The game ends when the correct combination has been guessed or all attempts have been used up. If the code breaker has guessed the combination, he wins; otherwise, the code master wins.
Vary the level of difficulty: If you want to make the game more challenging, increase the number of colors to increase the challenge. Or allow colors to appear more than once - this gives you even more opportunities to vary the combination.

Agree clear rules of the game: To ensure the game runs smoothly and remains fair, you should make agreements in advance. Decide whether colors may appear twice and how many attempts are allowed. Such small adjustments can significantly increase the fun of the game.
