Every guess is rated position by position — right digit in the right spot, right digit in the wrong spot, or digit not in the code. Six tries count toward your score; after that, keep going in free play or reveal the code. 1. 1 The secret code is 5 digits from 0 to 9, repeats allowed. 2. 2 Submit a complete code on every try. 3. 3 Each position is rated: correct, present elsewhere, or absent. 4. 4 Six tries count toward your score; a joker reveals one digit for a few points. ## Why play? - Pure deduction, with no vocabulary required. - Position-by-position feedback rewards a method. - Works at any age. ## Tips - Open with 01234, then 56789: after two tries every one of the ten digits has been tested once, and you already know which ones are in the code. - Watch out for repeats: the code can contain the same digit twice. If you double a digit and only one lights up, the grey marks the extra copy, not a missing digit. - An orange digit also tells you where it isn't: move it to a position you haven't tested yet on each try to pin it down in as few moves as possible. - Make every try count: keep your greens in place and fill the other slots with digits you haven't tested yet, rather than replaying greys. - The joker reveals the digit at a position you don't know yet and locks it in. It costs points, so keep it to settle between two hypotheses late in the game. ## Frequently asked questions
How do you play Decrypto? Enter a 5-digit code using 0 to 9. Each position turns green if the digit is in the right spot, orange if it's in the code but elsewhere, grey if it isn't in the code. You have 6 tries to find the full code, and a joker can reveal a digit.
Is Decrypto free to play? Yes. Decrypto is free and runs in your browser, on desktop or mobile, with nothing to download. You can play today's grid without an account; a free account unlocks the archive of past days. SIWA+ (€18 a year) removes ads and adds advanced stats.
How is Decrypto different from Mastermind? It follows the Mastermind idea, with digits instead of colours. The difference: Decrypto rates each position separately, like Wordle, instead of giving an overall count of right and misplaced pegs. Deduction is more direct, but you only get 6 tries.
Can the Decrypto code contain the same digit twice? Yes, repeats are allowed: 4 4 0 7 4 is a valid code. The feedback accounts for it: a digit is only flagged as many times as it actually appears in the code, and any extra copies in your guess show up grey.
What happens if I don't crack the code in 6 tries? The game counts as lost and its score is capped. You can then keep searching just for fun, with no points, or reveal the secret code straight away. A new grid is waiting the next day, at midnight your local time.
