The Crack the Code daily puzzle asks you to deduce a single three-digit code from two compact clue rows that report exact-position matches and wrong-position matches separately, and the only valid solution is 507. Each clue row carries two numbers, one for exact (correct digit at the correct index) and one for wrong place (correct digit, wrong index), so the puzzle rewards careful reading rather than guessing. A leading zero counts as a normal digit, the search space covers every code from 000 through 999, and the answer has been independently verified to be unique. The reward for finding that unique code is exactly 1,000 points, with no speed bonus and no penalty for an earlier wrong guess. Because the fixture is finite and runs entirely in the browser, the same clue rows and the same answer remain available after the page loads, which makes the puzzle a natural fit for a short daily mental exercise.
How the Two Clues Encode the Solution
Two clue rows drive the entire deduction. The first compares 527 against the answer and reports 2 exact, 0 wrong place. The second compares 750 and reports 0 exact, 3 wrong place. Together they pin down three facts at once: the digits 7, 5, and 0 all appear somewhere in the code, none of the unmatched 5, 2, or 7 sits in its guessed position from the first clue, and the placement of every digit is determined once the two exact slots are filled.
Worked scoring for the first clue, 527 against 507: at position one, 5 matches 5 (exact); at position two, 2 differs from 0 and 2 is absent from the answer (not exact, not present); at position three, 7 matches 7 (exact). The unmatched answer digits are {0} and the unmatched guess digits are {}, so the wrong-place total is 0.
Worked scoring for the second clue, 750 against 507: at position one, 7 differs from 5; at position two, 5 differs from 0; at position three, 0 differs from 7. No position is exact. After exact removal the remaining answer digits are {5, 0, 7} and the remaining guess digits are {7, 5, 0}. Each digit frequency is 1 in both sets, so the per-digit minimum is 1 for 7, 1 for 5, and 1 for 0, totalling 3 wrong place.
Solving the Crack the Code Daily Puzzle
The route from clues to the correct code takes only a few steps. The page presents three slots, a ten-digit keypad, and the two clue rows at the top, and the rest is mechanical. A short, disciplined run normally reaches the 1,000-point finish in a couple of minutes.
- Read both clue rows and note which counts are non-zero.
- Identify the digits that must be present: from clue 750's three wrong-place matches, the digits 7, 5, and 0 all belong to the code.
- Use clue 527's two exact positions to slot the digits 5 and 7 into their correct indices; with 507, position one holds 5 and position three holds 7.
- Place the remaining digit 0 into the only open slot, position two.
- Enter 507 by tapping the keypad or pressing 5, 0, 7 on the keyboard; the three slots fill from left to right.
- Submit by tapping the Submit button or pressing Enter; the score should jump to exactly 1,000.
- If your guess is wrong, edit the input with Backspace or Delete, or tap Clear guess to empty it, then try another candidate.
- If the same wrong code is resubmitted, no new history entry is created and no second error is consumed.
- Press Reset run to restore the original clues, empty history, and zeroed score at any point.
The full route from open page to 1,000 points stays small because the scorer only ever needs to verify the multiset rule, which is described next.
Score Outcomes by Player Action
The puzzle records attempts and freezes the run on two terminal events. The table below summarises every action the player can take against the in-page state.
| Player action | Effect on attempt history | Effect on score or feedback |
|---|---|---|
| Incomplete submit (0, 1, or 2 digits) | Not recorded as an attempt | Status copy shows positions remaining; no score change |
| Identical wrong code resubmitted | No new entry; same state reference returned | No second error consumed; feedback unchanged |
| First distinct wrong complete code | Recorded once; remains repairable | Distinct codes listed; run continues |
| Second distinct wrong complete code | Deadlocks the run | Unique answer disclosed; all inputs freeze |
| Correct code 507 submitted | Recorded as final entry | Exactly 1,000 points awarded; score and inputs frozen |
Deadlock and completion are both terminal, which is why the page exposes a Reset run control alongside the shared Restart control.
Why Multiset Accounting Rules the Wrong-Place Count
The wrong-place total is calculated per unmatched digit, not per slot. The scorer first removes every exact pair, then compares frequency counts for the unmatched answer and guess digits. This order prevents a repeated guess digit from reusing one answer position and inflating the total.
Consider guess 500 against answer 507. At position one, 5 matches 5 (exact). At position two, 0 matches 0 (exact). At position three, 0 differs from 7, and that 0 can no longer contribute because the single 0 in the answer has already been matched by the exact pair at position two. After exact removal the remaining answer digits are {7} and the remaining guess digits are {0}. The frequency minimum for 0 is min(0, 1) = 0, so the wrong-place total is 0. If the scorer counted the two zeros in the guess as two matches against the single remaining 7, the count would be 2 instead of 0, an obvious inflation.
This is the same logic the release test applies across every candidate from 000 through 999 to lock the answer on 507. For a deeper look at how repeated digits interact with this rule across similar deduction games, see how repeated digits are scored in a digit deduction game.
Why 1,000 Points Is Fixed, Not Variable
The reward for finding the unique code is exactly 1,000 points, by design. There is no speed bonus, no clue multiplier, no partial credit, and no penalty for which first wrong code was tried. A correct solution entered on the first attempt and a correct solution entered after one distinct wrong guess both receive the same fixed score.
The product contract treats the score as entertainment behaviour rather than a reasoning measurement. The original fixture is fixed, the finite error rule is disclosed, and the unique solution is proved by exhaustive enumeration, so the score is intentionally simple. Players who want a fixed daily target can plan around 1,000 points without tracking time, attempts beyond the second wrong code, or order of guesses.
Controls, Offline Play, and Boss Mode
Input is symmetric across touch and keyboard. Tapping a digit on the ten-digit keypad appends from left to right until all three positions are filled. Pressing the physical 0 through 9 keys does the same. Backspace or Delete removes the final entered digit, and Enter submits the current input. Clear guess empties only the current input, leaving the attempt history and score untouched, while Reset run restores the entire game including attempt history and terminal state.
Non-digit programmatic input and a fourth digit are rejected at the logic boundary before any attempt is recorded, and the visible controls prevent both cases before submission. Repeated keyboard events are ignored at the UI layer, while state-level deduplication provides a second guard for repeated complete guesses. The shared double-Escape Boss Mode temporarily replaces the puzzle with a neutral spreadsheet view, and returning from Boss Mode preserves the same code, wrong history, score, and terminal status.
Everything runs locally in the browser. No code guess, clue interaction, score, or keyboard event is uploaded, and no account, paid service, network request, random generator, or new runtime dependency is used. Because the complete fixture is bundled and finite, the same clue rows and unique answer remain available offline after the page loads. The interface is accessible without colour: clues state their counts in text, slots show a digit or underscore, distinct wrong codes are listed, and status copy gives both used errors and entered digits. All keypad buttons carry native semantics and at least a touch-friendly minimum height, and five columns fit comfortably at a 390-pixel viewport without page overflow.
Making It Part of a Daily Puzzle Habit
The fixed fixture is what makes the Crack the Code daily puzzle workable as a recurring routine. The clue set does not rotate, the answer does not change, and the search space is small enough to verify by hand, so a short session can become a fixed checkpoint in a daily mental exercise block.
A practical routine looks like this: open the page, read both clue rows aloud, identify the three present digits, slot the two exact digits from 527 into the first and third positions, place the remaining digit into the second position, submit 507, and confirm the score reads 1,000. Players who want the deduction to feel fresh can mentally hide the answer and work from the multiset rule alone. Reset run starts a clean state for the next session without page reload, which keeps the habit sustainable on busy days.
