Yellow Lines

Flick a glowing line across the dark void, release to send it flying, and watch it ricochet off walls until every target shatters in a burst of color.

The first thing you'll notice about Yellow Lines is how little it asks from you—drag, release, done. But that simplicity hides a surprisingly tricky little puzzle. You're aiming a bright line through dark space, trying to make it bounce off surfaces and clip every shape on screen before you run out of shots. I've lost count of how many times I thought I'd solved a room only to miss a single triangle hiding in the corner. Each level sets up a different geometry problem. Sometimes the line needs to bank off two walls at once; other times you need to feather the angle so it slips through a narrow gap. The drag mechanic gives you a live preview of the first segment, but once it leaves your finger, chaos takes over. That's where the joy is—watching your line spin around a room like a racquetball, snapping targets as it goes. If you've ever played those old vector bounce games, this scratches the same itch, but with cleaner controls and a sharper visual style. What kept me coming back wasn't the challenge so much as the rhythm of it. You get into a flow: aim, release, watch, reset. The levels are short, so failing doesn't sting; you just try a slightly different angle. It's the kind of game that's perfect for a five-minute break but quietly turns into thirty. No unlocks, no ads-splosion, just one idea done well. And the sound design deserves a mention—each bounce and shatter has a crisp little click that makes even a miss feel satisfying.

Touch and drag to aim, release to shoot.

Aim for the first bounce point, not the target — a good bank off a wall often covers more of the screen. Use the drag preview to set a shallow angle when you need the line to zigzag between multiple targets. Don't waste shots on single targets if a single line can chain them together; patience beats speed. If a level seems impossible, try aiming at a corner where two walls meet — the line can bounce back on itself and cover blind spots. Pay attention to the target shapes: some are positioned to force a double or triple bounce, so count the angles before releasing. You can often reset faster by dragging from the starting point again rather than waiting for the line to stop.
