Connect the water.
Fill every ball.
Aqualine is a free pipe puzzle game. Water starts from one source. Rotate the pipes so it flows through the whole network and fills every empty ball. Every level is different, and the levels never end.
▶ PLAY NOW
Aqualine is still a work in progress. You can play it here in your browser today. We are working on an Android app and plan to release it on Google Play later.
How to play
- Tap a pipe to turn it a quarter turn.
- Line the pipes up so water can travel from the glowing source tank through the network.
- Water splits at T and cross junctions, so one source can feed many balls.
- The level is complete only when every ball is full and every pipe is connected with no open ends.
What makes it fun
- Endless levels. Boards grow from 4×4 up to 7×10, with more balls and more branching as you go.
- Always solvable. Every level is built from a working solution, then shuffled.
- Fewer moves, more points. Earn weekly points and badges for solving levels in few moves.
- Hints and undo. Stuck? Use a hint, or undo your last turn.
Tips
Start from the source and fix pipes one by one along the water’s path. Watch the T and cross junctions: one of their openings brings the water in, and the others carry it onward. Pipes that glow red have an opening that does not match its neighbour.
