Just gather each color of ball onto its matching LINE. Swaplines is a simple puzzle game you can understand at a glance.

Easy to pick up, satisfying to master

Drag a LINE to spin its balls around.

Click a switch between two LINEs to swap the balls facing each other.

That's all there is to it. Fill every LINE with its own color to clear the board.

It may feel like trial and error at first, but the more you play, the more the tricks click into place, and the more you can feel yourself getting better.

Endless, randomly generated puzzles

Every puzzle is freshly generated and always solvable, so you will never run out.

Solve puzzles, grow a town

There is always a cute little town in the background. Every puzzle you solve adds another house, and before you know it, it has grown into a big city.

As many saves as you like

Create as many saves as you like. Every save grows its town in its own way, so there is always a new town to watch take shape.
