How to Play

Crack the secret 4-color code in 7 guesses or fewer.

Making a guess

Tap a color circle or type its number (1–6 on Easy, 1–9 and 0 on Hard) to fill the row. Use ⌫ to undo the last pick, or Clear to restart the row. Tap Submit or press Enter when your 4-color guess is ready.

Reading the feedback

After each guess, up to 4 small pegs appear on the right:

  • ● Red — correct color and position
  • ● White — correct color, wrong position
  • ● Black — color not in the code at all

The pegs only tell you how many — not which positions were right.

Difficulty

Easy uses 6 colors (1–6). Hard uses all 10 (1–9 and 0). The secret code never repeats a color; your guesses can't either.

Daily vs Practice

Daily — one shared puzzle per day. Easy and Hard are separate puzzles. Progress saves automatically; return any time to finish.

Practice — unlimited random games. Use New Game to try a fresh code. Results can't be shared in Practice mode.

Scoring

Scores are 0–100. A perfect game — cracking the code on the very first guess — scores 100. Solving in more guesses scores progressively less, with the bonus for finishing early weighted heavily. If you don't crack the code, you still earn a small consolation score based on the reds and whites you found along the way.
