Dot Lines

Drag a glowing thread between matching dots, but flinch for a second and another color slices your line clean in half.

Dot Lines looks simple at first: a handful of colored dots scattered on a plain grid. You press one, drag to its twin, and watch a pipe snap into place. Then a new dot appears and you realize that path you just laid can get chopped by any other line crossing it. That's when the old arcade tension kicks in—you're not just solving, you're defending space. I kept losing on the later levels because I'd get greedy, dragging a long zigzag pipe across the whole board. Then some red line cuts right through my blue path and the connection fizzles. The proper way is to hug walls, loop outward, keep your fingers moving fast. There's a weird satisfaction when you thread a line through a tiny gap just before a rival color reaches it. The touch and drag controls feel tight—no accidental drops, even on a phone. It's a speed puzzle with bite. Visually it's nothing fancy: bright solid colors, clean grid, dots that pulse to tell you where to go. But that's all it needs. You'll replay a board half a dozen times, tweaking route order, because losing doesn't feel cheap. It feels like you misread the board. And that's a rare thing in a free browser game.

• Connect the holes with same-colored pipes! • Be careful! The dots can be cut off by other dots! • Touch and drag.

Start with the longest distances first—they set the frame for everything else. Keep each pipe as close to the outer edge as possible to avoid cut-throughs. Watch the blinking dot: it shows which color is about to spawn, so pre-clear a path. Don't drag across the center unless you have to; the middle is a slaughterhouse. If a line gets severed, release immediately and let it fade before redrawing. On mobile, use a stylus or your thumb nail for tighter cornering.
