Getting started with Mastermind
Take a moment to check the current turn. Deduce a hidden four-colour code within ten guesses, using exact and misplaced feedback. The game area remains available above the explanation. The computer chooses four positions from six colours; repeated colours are allowed. Try the rule on the board, then read the next instruction.
Four positions, six colours and ten guesses, with repeated colours allowed. This is an independently coded free colour-code puzzle, not an official branded edition.
Practice beyond the first move
Keep the goal in view while choosing a move. Check guess records your attempt. Exact means correct colour and position; misplaced means correct colour in another position. Start a new round when you are ready to try again.
The goal to keep in mind
Deduce a hidden four-colour code within ten guesses, using exact and misplaced feedback. Try the rule on the board, then read the next instruction.
Follow these playing steps
- The computer chooses four positions from six colours; repeated colours are allowed.
- Select a code position and then choose a colour. Fill all four positions.
- Check guess records your attempt. Exact means correct colour and position; misplaced means correct colour in another position.
- Each secret peg can match only one guess peg. Use the feedback to narrow the next guess.
- Find all four exact positions to win. After ten unsuccessful guesses the secret code is revealed.
Controls
Keep the goal in view while choosing a move. Tap one of four positions, then a labelled colour button. Numbers identify colours as well as the swatches. Press Check guess only when all slots are filled.
A closer look at one example
The example and rules describe the same game you can play above. For secret 1,1,2,2 and guess 1,2,1,3, feedback is one exact and two misplaced. The extra 3 has no match.
An important reminder
Read the position before choosing your next action. Four misplaced matches do not mean four exact positions. Also, repeated colours must not be counted more times than they appear in the secret. Try the rule on the board, then read the next instruction.
