Ladder answer

• LARGE 5 letters
• REGULAR 7 letters — adds two letters to the rung below
• GUERRILLA 9 letters — adds two letters to the rung below

LARGE sits inside REGULAR, which sits inside GUERRILLA — the two letters added at each rung are the whole puzzle. Scrambles shown that day: LAGRE · UGERLRA · LILGRRUEA.

LockCode answer: 2918

The clues and what each one tells you:

1. 0418: 2 in the right place, 0 in the wrong place — 2 of 0, 4, 1, 8 are in the code.
2. 1905: 1 in the right place, 1 in the wrong place — 2 of 1, 9, 0, 5 are in the code.
3. 4591: 0 in the right place, 2 in the wrong place — 2 of 4, 5, 9, 1 are in the code.
4. 7953: 1 in the right place, 0 in the wrong place — 1 of 7, 9, 5, 3 are in the code.
5. After all clues, 2 codes remain possible.

With 2 candidates left, a good second guess splits them by feedback so the third guess is forced. Read the LockCode strategy guide for the method.
