Flow Lines: Connect Puzzle

Flow Lines is a calm, satisfying connect-the-dots puzzle. Drag to join each pair of matching colored dots with a pipe — but here's the catch: your pipes can't cross, and you must fill EVERY square on the board. Simple to learn, wonderfully hard to put down. Start easy and work up to brain-bending boards with dozens of colors, irregular shapes, and cross-over bridges where two pipes pass over and under each other. FEATURES • Pure, relaxing gameplay — no timers (unless you want them), no clutter, just you and the puzzle. • 7 handcrafted level packs, from gentle 5×5 starters to expert 8×8 boards. • BRIDGES — a cross-over twist: route two pipes straight through the same cell, one over, one under, without connecting them. • SHAPES — irregular boards with blocked cells for an extra challenge. • DAILY PUZZLE — a fresh board every day, build your streak, and share a spoiler-free result with friends. • ENDLESS MODE — puzzles that adapt to your skill and never repeat. • PUZZLE RUSH — how many can you solve in two minutes? • CREATE & SHARE — build your own levels (with walls and bridges), validate them instantly, and share them as a short code. Play codes your friends send you. • EARN COINS & CUSTOMIZE — unlock board themes and pipe/dot skins. • Light and dark themes, sound, haptics, and colorblind-friendly symbols. • Helpful hints when you're stuck, and unlimited undo. Whether you've got two minutes or two hours, Flow Lines is the perfect way to unwind and keep your mind sharp. Download free and start connecting! Flow Lines is free to play with ads.
