It is a reproduction of the simple game Guess, being developed using Avalonia UI. Which also means it's cross-platform.

It's the same as the original one:

• Pick 4 balls out of 6 different colors, while the color of balls can be the same.

• Submit your guess, and observe the feedback:

  • A green indicator means a ball of correct color in the right place
  • A yellow indicator means a ball of correct color in the wrong place
  • A red indicator means the ball does not appear at all

  Note the position of the indicator is irrelevant

• Make another guesses based on the provided information

• A player has at most 10 trials in a single game
