About Code Crack
The classic code-breaking duel of pure logic. A secret sequence of four colours is waiting; each guess earns pegs — white for right colour in the right spot, purple for right colour in the wrong spot. Colours can repeat, which is where careless guessers come unstuck. Ten rows to crack it. Deduction, elimination and a little nerve. Free to play in your browser — no download, no sign-up.
How to Play
Tap colours to fill the four slots, then hit Check. White peg = right colour, right position. Purple = right colour, wrong position. Colours may repeat. Crack the code within 10 guesses.
Tips & Strategy
Open with two pairs (say red-red-blue-blue). Repeats in your first guesses tell you how many of each colour exist, which single-colour spreads can't.
Pegs are anonymous — they don't say which slot is right. Change one thing at a time between guesses when you're narrowing down positions.
Zero pegs is gold: every colour in that guess is completely absent. Cross them all off and the puzzle collapses fast.
Before each guess, ask: is this consistent with every previous row of pegs? A guess that contradicts old feedback is a wasted row.
