EXPERTThe Silent Lock
Find the only ordered code of 5 digits.
Materials: Pencil, gum and gridded paper; no commercial game required.
Rules you need
- Each position contains a number from 0 to 7. Repeats are allowed. The code has exactly 5 positions; an initial zero is allowed.
- "Good place" includes the positions whose number and place are correct. "Unplaced" counts the other numbers present, respecting the multiplicity.
- To count the wrong placed, first matches the well placed numbers, then each remaining occurrence at the most once. The indices do not give the location of the incorrectly placed numbers.
- All indices are simultaneously true. There is no hidden information about colors, parity or missing numbers.
The puzzle
The table reads from top to bottom. The proposals are tests and are not already confirmed number positions.
Write down the possible multiplicities of each number, then look for arrangements compatible with all scores.
| L / C | 1 | 2 | 3 | 4 |
|---|---|---|---|---|
| 1 | Test | Guess | Exact matches | Misplaced matches |
| 2 | 1 | 22543 | 1 | 3 |
| 3 | 2 | 41050 | 1 | 0 |
| 4 | 3 | 70302 | 1 | 2 |
