Crack the Code has one fixed puzzle rather than multiple difficulty levels: the three-digit solution is 507, and submitting it earns exactly 1,000 points. For readers searching “crack the code difficulty levels,” the important distinction is that this is one deterministic challenge, not a rotating ladder of easy, medium, and hard rounds. The original fixture uses two clue rows, and Reset run returns the same clues and answer in a clean state. In the linked Crack the Code, an exact match means the digit and position are both right; a wrong-place match means the digit is present elsewhere after exact matches are removed. You can enter by touch or physical number keys, and submitting fewer than three digits does not spend an attempt. One distinct wrong complete code can be repaired, but a second distinct wrong code deadlocks the run. The correct code receives the same fixed 1,000 points with or without that first error: there is no speed bonus, partial credit, or error penalty. An independent check of every zero-padded candidate from 000 through 999 confirms that 507 is the only solution.

What “difficulty levels” means here
The search phrase may suggest a tier list, but this game presents one fixed challenge rather than separate easy, medium, and hard levels. The challenge comes from combining exact-position clues with an error rule that allows only one distinct wrong complete code to be repaired. Reset run and the shared Restart control restore a clean state without replacing the clues, so another round replays the same puzzle rather than moving to a new tier.
| Feature | Defined behavior | Effect on play |
|---|---|---|
| Challenge structure | One original, deterministic three-digit fixture | The clues and solution remain unchanged after a reset |
| Code space | Every zero-padded code from 000 through 999 | A leading zero is treated as a normal first digit |
| Clue set | Two fixed rows describing guesses 527 and 750 | Both rows must be satisfied together |
| Completion score | Exactly 1,000 points for the correct code | No speed bonus, partial credit, or score penalty |
| Error rule | One distinct wrong code is repairable; a second distinct wrong code deadlocks the run | Reset run is required after the second distinct error |
The clue set is fully product-authored rather than copied from a published puzzle, external database, branded board game, or rotating challenge feed. Its fixed 1,000-point result is recreational product behavior, not a standardized intelligence, education, employment, health, or psychological assessment. Describing this particular puzzle as easy or difficult is therefore a personal description, not an official difficulty classification.
Read exact and wrong-place counts separately
Every clue row combines two distinct ideas. An exact match means the guessed digit equals the solution digit at the same index. A wrong-place match means that an unmatched digit occurs elsewhere in the solution. The scorer first removes all exact pairs, then compares the remaining digit frequencies. For each digit, it counts only as many wrong-place pairs as the unmatched solution and guess can support. This prevents one solution position from being used twice or counted once as exact and again as misplaced.
| Earlier guess | Exact | Wrong place | What the row establishes |
|---|---|---|---|
| 527 | 2 | 0 | The first and third positions are exact, while 2 is absent |
| 750 | 0 | 3 | All three digits are present, but every guessed position is displaced |
The duplicate-safe order matters whenever a digit appears more than once. A repeated guess digit cannot claim the same remaining solution position twice. Also, a wrong-place total does not label the final destination of each digit; it only reports how many unmatched digits can be paired elsewhere. You still need to combine both clue rows to determine their order.
Solve and submit the fixed code
- Open the game and locate both clues. Each row describes an earlier guess rather than a code you are required to reuse.
- Read the 527 row. Its result is two exact matches and zero wrong-place matches. Those exact positions place 5 in the first slot and 7 in the third slot, while 2 does not appear in the solution.
- Read the 750 row. Its result is zero exact matches and three wrong-place matches. Therefore, 7, 5, and 0 are all present, but each occupies a different position from the one shown in that clue.
- Combine the two constraints. The first slot is already fixed at 5 and the third at 7. The remaining digit must be 0, so the complete code is 507.
- Enter all three digits. Tap or click 5, 0, and 7 on the keypad, or press those physical number keys. The digits fill the three visible slots from left to right.
- Submit the completed entry. Press Enter or use the submit control. Entering 507 awards exactly 1,000 points and creates a terminal completion state.
- Repair an accidental first error if necessary. After one distinct wrong complete code, use Backspace, Delete, or Clear guess to edit the entry and try another candidate. After a second distinct wrong code, the answer is disclosed and the controls freeze until Reset run or the shared Restart control begins again.
Use repair actions without losing the run
The three slots fill from left to right. Digit buttons and physical keys from 0 through 9 behave identically. Backspace or Delete removes the final entered digit, while Clear guess empties only the current input and preserves the run’s attempt history. Submitting zero, one, or two digits reports how many positions remain but records no wrong attempt. A fourth digit is rejected without partial entry, and non-digit programmatic input is blocked at the logic boundary.
| Action or submission | Result | Attempt effect |
|---|---|---|
| Submit fewer than three digits | The status reports the number of positions still empty | No error is recorded |
| Submit the first distinct wrong complete code | The code is recorded once and the input remains repairable | One distinct error is used |
| Submit the identical wrong code again | The game returns the same state without duplicating history | No additional distinct error is used |
| Submit a second distinct wrong complete code | The answer is disclosed and digit, deletion, clearing, and submit actions freeze | The run reaches a terminal error state |
| Submit 507 | The score becomes exactly 1,000 and the score, code, history, and feedback freeze | The run completes successfully |
| Use Reset run or shared Restart | A clean state is restored, including the input and attempt history | A fresh replay begins |
“Distinct” is important because repeatedly submitting the same wrong code is an atomic no-op rather than another error. A correct solution after no errors and a correct solution after one distinct wrong guess both receive exactly 1,000 points. The identity of that first wrong candidate does not change the award. Completion is terminal as well, so a successful run also requires a reset before another attempt.
Why 507 is the only solution
The uniqueness claim is exhaustive rather than based only on displaying an answer. Release validation defines a literal version of the clue table, performs exact-position removal, builds separate unmatched frequency maps, zero-pads each integer from 000 through 999, and filters the full candidate set. Only 507 satisfies both clue rows. The production result is then compared with that separate one-element result set.
This independent traversal also confirms why the puzzle remains fixed offline after the page has loaded. The scorer does not need a random generator or a live puzzle feed, and the same clue rows and unique answer remain available offline after the page loads. Because the page discloses both the solution and its proof, later replays are for entertainment rather than an unaided reasoning test.
Play on touch or keyboard, locally
The interface does not depend on color. Clue counts appear in text, empty slots use underscores, wrong codes are listed, and status copy reports entered digits and used errors. All keypad buttons have native semantics and touch-friendly dimensions. Five control columns fit at a 390-pixel viewport without horizontal page overflow, while physical number keys provide the same entry path as the on-screen controls.
Everything runs locally in the browser. No code guess, clue interaction, score, or keyboard event is uploaded, and the fixed puzzle remains available offline after loading. No account or paid service is required. The shared double-Escape Boss Mode temporarily replaces the puzzle with a neutral spreadsheet view, but returning preserves the code, wrong history, score, and terminal status.
Best practical order: identify the digits from the all-wrong-place clue, anchor them with the exact positions from the other clue, verify all three slots, and only then submit. Entering too early is safe, but the first complete mistake still matters because the next distinct complete mistake ends the run.
