Flow Line

Flow Line is a neon-themed puzzle game where players connect matching colored nodes on a grid by drawing continuous paths that must not cross each other. The game features progressively harder levels with special mechanics such as portals, dark stages, and numbered blocks. Players earn stars to unlock trail themes or enjoy simpler challenges in Zen Mode. It is playable on both desktop and mobile devices directly in the browser without any downloads.

The core gameplay involves drawing lines between matching nodes on a grid. Players must plan routes to ensure lines do not cross and fill all empty spaces. Advanced levels introduce portals (teleporting lines), dark stages (hidden areas), and numbered blocks (requiring exact step counts). Completing levels earns stars to unlock new trail themes. Zen Mode offers a stress-free freeform experience.
