Why 2 moves is the minimum.

BOOM differs from POOP in 2 letter positions, so any route needs at least 2 changes. This route meets that lower bound.

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.
