Neumorphism vs Hanbut

The tapped panel and its top, bottom, right, and left panels are toggled. Can you turn off all the panels?

Hanbut is a puzzle drawn in a single brushstroke on paper. Start at 1 and move up, down, left or right, passing the numbers in order. Fill every cell exactly once and finish on the largest number to complete the page. Walls can't be crossed, and no cell can be visited twice. ■ A puzzle without mistakes Stuck? Just trace your line back. No mistake counter, no hearts, no countdown — and any valid path counts. ■ Ink that feels real Press slowly for a thick, wet line; sweep fast for a thin, split, dry-brush stroke. Fresh ink glistens, then settles and dries. Each cell answers with a soft brush sound and a gentle tap. ■ Today's Hanbut Everyone draws the same page each day.
