There is exactly one shortest route in this checked word list.

Which first moves work?

One next word keeps you on a shortest route from COSH: COST.

The table lists all 10 accepted one-letter neighbors. “Moves remaining” starts after that first move. “Total via this word” includes it, so you can compare that choice with the 4-move minimum.

Why 4 moves is the minimum.

COSH differs from POOP in 3 letter positions, so any route needs at least 3 changes. The accepted intermediate words require a longer route: the first complete connection in our search occurs at 4 moves.

The solver searches the checked word graph in distance order. It reaches every word one move away before trying two moves, then continues until it reaches POOP. The minimum applies to this word list; another game or dictionary may accept different connections.

Our Easy label uses distance only: up to 5 moves is Easy, 6 is Moderate, 7 is Tricky, 8 is Hard, and 9 or more is Expert. It does not measure how familiar you will find each word.
