Ink Ladder answer

How Ink Ladder puzzles are built

Every pair is generated from the date. The generator picks a start word, walks the graph of all common four-letter words connected by single-letter changes, and chooses a target that sits exactly four steps away. That distance is the par, and because it comes from a breadth-first search it really is the shortest chain that exists — not an estimate.

Solving without the answer

If you would rather not use this page tomorrow, three habits do most of the work:

1. Work from both ends. Build two rungs down from the start and two up from the target, then look for a word that joins them. Four-step ladders almost always meet in the middle.
2. Move the vowel. The vowel slot has more neighbours than any consonant slot, so changing it keeps your options open. Locking it early is the usual cause of a dead end.
3. Fix one letter at a time. A rung that suddenly matches two letters of the target is normally a detour. Optimal chains tend to correct a single position per step.

Why some days are much harder

Word-ladder difficulty is not about vocabulary, it is about graph shape. Some four-letter words sit in dense neighbourhoods with a dozen neighbours, and ladders through them feel effortless. Others sit on thin bridges where exactly one word connects two regions of the graph, and the whole puzzle collapses to finding that single word. A hard day is usually a bridge day.
