Lumio is a calm, beautiful connect-the-dots puzzle. Join each pair of colored dots with a glowing line, fill every cell of the grid, and never let the lines cross. Easy to learn, deeply satisfying to master.
✨ SIMPLE TO PLAY
Drag from a dot to draw a line to its partner. Lines can't cross, and every cell must be filled. Made a wrong turn? Drag back to shorten your line, or draw straight through another one to cut it.
🧩 EVERY PUZZLE HAS ONE PERFECT ANSWER
Every level is built and checked so it has exactly one solution. No guessing: every move can be worked out, and every solve feels earned.
🌙 CALM BY DESIGN
Soft shapes, glowing lines that follow your finger, gentle chimes and subtle haptics. Dark and light themes. No timers, no pressure: play at your own pace, one-handed.
💫 SO SATISFYING
Hear each pair chime into place, feel it click, and watch the whole board light up when you solve it. Silky-smooth drawing at up to 120 Hz on supported phones.
⭐ GO FOR PERFECT
Solve a level in one stroke per color, without hints, to earn a star. Stuck? Use a hint to reveal one line.
📈 ONE GENTLE JOURNEY
