Ink Flow

A Flow Free path puzzle, themed as tracing neon ink lines. Each colour has two ink dots. Drag from a dot through the adjacent empty cells to trace its line to its matching dot. Lines can't cross or overlap, and you must fill every cell. Tap a dot to clear and redraw its line. Connect every colour to finish the piece. 10 designs grow from 5×5 / 3 colours up to 7×7 / 7 colours.
