Line Connect Game

Line Connect is a quiet logic puzzle: each level gives you a scattered layout of dots and pins, and your job is to draw a single continuous line that touches everything you're meant to touch without ever crossing itself. It sounds simple until the board fills up with fixed nails that can't be moved, forcing you to route your line around them instead of straight through.

There's no timer pushing you along, so most of the challenge is visual — staring at a tangle of pegs and working out the one path that threads through cleanly. Levels start as short warm-ups and slowly add more obstacles and tighter spacing, so the same basic rule (don't cross your own line) keeps producing new kinds of puzzles.

Controls

Tap and hold on a line to drag it into place — that's the entire input scheme, and it works the same way with a mouse on desktop or a finger on phone and tablet.

Tips

• Plan around the fixed nails first — since they can't move, they effectively decide which routes are even possible before you draw anything
• If a level feels stuck, try starting from a different dot; the order you connect things in often opens up a path that wasn't obvious from the first dot you tried

Good pick for a few quiet minutes of untimed puzzling rather than anything reflex-based.
