❓ FAQ
Is this the clinical Tower of London?No. Clinical versions have fixed problems, peg heights and scoring rules. This is a five-puzzle original.
What does planning mean here?Think a few moves ahead before tapping. That feeling is not an executive-function diagnosis.
Why a move limit?To discourage random shuffling. The cap is a toy rule, not a published cut-score.
