What This Game Is

Guess is a self-contained logic puzzle built around one clear objective. Each new board gives you a fresh problem to solve, so it works well for quick sessions and repeated play.

Guess the hidden combination of colours.

How to Play

This game can be played with either the keyboard or the mouse. With the mouse, drag a coloured peg from the tray on the left-hand side to its required position in the current guess; pegs may also be dragged from current and past guesses to copy them elsewhere. To remove a peg, drag it off its current position to somewhere invalid.

Most puzzles in this collection reward deduction more than speed. Focus on the most limited choices first, use the clues to narrow the board, and avoid guesses unless the puzzle mode clearly expects them.

Beginner Tips

  • Start with the area that has the strongest clue or the fewest legal options.
  • Use marks, notes, or temporary indicators if the puzzle supports them.
  • Try to preserve flexibility instead of committing too early when multiple moves look possible.
  • If the board gets messy, restart a fresh puzzle and apply what you learned from the first run.
