New: discover Fair Game, this game and 10 more puzzles in one app. Small fixes.
Connect the dots with pipes, fill every cell. Bridges and one-way gates.
A grid holds pairs of coloured dots. Drag from a dot to its twin to draw a pipe, and link every pair. Pipes can't cross: drawing through another pipe cuts it. Linking everything is the easy part. A perfect board also fills every single cell, and that takes a plan. ONE SOLUTION, NO GUESSING Every board has exactly one way to link all the colours and fill every cell, checked by a solver. So every puzzle can be worked out by logic, and the hint is always right. BRIDGES AND ONE-WAY GATES A bridge lets two pipes cross: one runs over, one runs under, and a full board uses both lanes. A one-way gate only lets a pipe through straight and in the arrow's direction, so it decides which dot you have to start from. Classic connect-the-dots puzzles, made to think again. THREE STARS, ONE STROKE EACH Link every pair for one star. Fill every cell for two. Do it with one stroke per colour for three: see each pipe before you draw it. Drag back along a pipe to shorten it, or start from its middle to carry on. THREE WAYS TO PLAY Relax: short lessons first, then small boards and gentle links, with bridges from level 8. Hard: bigger boards with one-way gates. Expert: big boards with bridges and gates together. 600 solver-checked levels, then fresh boards for as long as you like. HELP WHEN YOU WANT IT Undo your last stroke (three free per level), get a hint that lays one correct pipe, or reveal the first step of every pipe. PLAY AT YOUR PACE No timer, no lives, no energy, no daily limits. Every level takes 30 seconds to a few minutes. Play fully offline. ADS AND THE ONE PURCHASE The game is free. After your first few wins, a short ad may play between levels, at most every third level and never in the middle of one. Hints, reveals and extra undos are optional rewarded ads that you choose to watch. The one purchase, Remove Ads, switches off the ads between levels for good; the optional rewarded helps stay available. No account, no sign-up. Your progress stays on your device.
