Light Route: One Line Puzzle

Light Route is a one-line path puzzle that grows with you. Start from the glowing node, pass each numbered checkpoint in order, fill every open cell, and reach the exit.

• 300 progressively generated levels from 4×4 to 8×8 • Blocked cells and ordered checkpoints steadily raise the challenge • Trace backward along your route whenever you take a wrong turn • Early puzzles allow multiple routes; the final 20 have a verified unique solution • Use hints when stuck, with optional rewarded ads for more hints • Free players may see one interstitial only after every five completed levels • A one-time purchase permanently removes interstitial ads
