Rung #17: DISK to JACK — the solution

The Rung ladder from August 31, 2026: DISK to JACK, one letter at a time, every step a real word. Par is 4: the shortest climb there is takes 3 rungs, and par gives you one to spare.

The puzzle

Climb from DISK to JACK. The shortest climb through the whole accepted dictionary, counting the leap — two letters changed in one move, once, at the cost of two rungs — is 3 rungs; par is one more, so the shortest route comes in under it. Without the leap the shortest climb is 4 rungs; the leap saves 1.

The walkthrough

A climb under par, the only one that short: at every step a single letter changes and every word on the way is one the game accepts.

1. DISK → DACK — the leap: I becomes A and S becomes C, two letters in one move for two rungs.
2. DACK → JACK — the first letter, D becomes J.

The answer

DISK · DACK · JACK — 3 rungs, the leap landing on the word in italics.
