The clues and what each one tells you:
- 3081 scored nothing, so 3, 0, 8, 1 are all out.
- 9286: 1 in the right place, 0 in the wrong place — 1 of 9, 2, 8, 6 are in the code.
- 3580: 0 in the right place, 1 in the wrong place — 1 of 3, 5, 8, 0 are in the code.
- 5194: 0 in the right place, 2 in the wrong place — 2 of 5, 1, 9, 4 are in the code.
- After all clues, 5 codes remain possible.
With 5 candidates left, a good second guess splits them by feedback so the third guess is forced. Read the LockCode strategy guide for the method.
