Reflow

Reflow is an evolving arrow puzzle. Find a clear exit among interwoven long paths, bends and short arrows. Every successful removal changes the remaining board, so your next move needs a fresh plan.

Explore 40 levels: random reversals at the start, eight-direction rotation from level 10, relocation from level 20, and changing widths that affect clearance from level 30. Preview a move to inspect its actual outcome before confirming. Hint, Undo and Restart help you explore the puzzle.

Controls: Click or tap an arrow with a clear exit. Use Preview a move to inspect the next arrangement. Use Tab to focus an arrow or control, then Enter or Space to activate it. Toggle sound with the speaker button.
