Free line drawing puzzles and pipe games
Everything in this section is solved by making a connection. Sometimes you draw it yourself, sometimes you rotate pieces until it appears, and sometimes you sketch a shape and let physics carry something along it. Line drawing puzzles and pipe puzzles make up most of the collection. What they share is a gap between two points, and a set of rules about how you are allowed to close it.
Connect & Draw games
All Dot Connect Puzzle Game
Connect every dot on the board in a single touch. Puzzle packs and a daily challenge, pitched as a few minutes of brain training.
Ball Connect
Link each pair of matching balls with a path through the grid, without crossing lines or running out of room.
Bright Connect
Link batteries to bulbs until every light is on, but only within the moves the level allows.
Catch The Hen: Lines and Dots
Connect dots into lines that fence in a hen. Every successful capture earns eggs.
Clever Crow
Toss pebbles and other objects into a long-necked jar until the water rises high enough for a thirsty crow to drink.
Connect Pipe! Color Puzzle Game
Join pipe ends of matching colours across the board without letting any two pipes cross. Timed and daily puzzles too.
Connect the Pipes: Water Puzzle
Turn pipe pieces so water reaches each drain, and mix coloured streams when a drain asks for a colour no source provides.
Dots and Boxes 2
The pen-and-paper game on screen: take turns drawing lines between dots, close boxes, and finish with more of them than your rival.
Dots Line
Connect every point in one unbroken stroke, without ever drawing along the same line twice.
Dots Master
Link neighbouring dots of one colour, close squares and loops to clear a whole colour, and meet each goal within the move limit.
Draw Line Stickman
A stick figure is surrounded by traps, enemies and falling objects. Study the scene and draw a barrier that keeps him safe.
Draw Path To Finish
Draw the route a heroine's moving platform will follow, then let go and see whether it clears the saws, fire and lava.
Draw the RailBall Physics
Build a track out of rails, planks, springs, accelerators and bumpers, then press start and see if the ball reaches the goal.

Flow Laser Quest
Join each pair of same-coloured points by sliding a path across a grid of squares, without crossing an earlier path.
Funny Cars Route
Draw a path from each car to the parking space of its own colour. Later levels ask you to park several cars at once.
Happy Bucket Challenge
The bucket is empty and unhappy. Draw a line that lets liquid pour into it, and aim for three stars on every level.

Line to Goal : Draw The Path
A football physics puzzle: draw the line a ball will follow, past bouncing walls, moving platforms and wind, into the goal.
Link Flow
Draw lines between dots until they match the pattern the level asks for, with undo and reset buttons for slips.
Neon Circuit
Spin tiles a quarter turn at a time until power runs from the source to every terminal. Beat par for three stars.

Click pipe pieces to rotate them until water reaches every plant on the board, then watch the plants come into bloom.
Water Flow Happy Glass
Draw with a pencil to steer water from a tap into a glass, and use as little ink as you can to earn all three stars.
About connect & draw puzzles
The classic form is the colour-pair grid. Two dots of each colour sit on a board, and you drag a path from one to its partner. Paths may not cross, so the first route you lay decides where every later one can go. Flow Laser Quest states that rule and gives you a hundred levels of it. Dots Line is the one-stroke kind instead: every dot must be joined in a single continuous movement, and no line may be drawn twice.
Pipe puzzles fix the pieces in place and let you turn them. The task is to rotate each piece until water, or power, runs unbroken from the source to everything that needs it. The pieces are straights, bends and junctions. Plumber World supplies fountains, houses, lakes and swimming pools as destinations. Neon Circuit swaps water for electricity across 40 levels in 8 zones, growing from 4x4 grids to 8x8, and gives three stars for beating par. One jungle-themed game lowers its timer with every move, so turning pieces at random costs you points.
The drawing physics games work differently, because whatever you draw becomes a solid object in the level. In Water Flow Happy Glass a pencil line steers water from a tap into a glass, across five themed worlds, and the less ink you use, the more stars you earn. Other games here follow a similar pattern with a bucket or a glass of juice. Clever Crow involves no drawing at all. You throw stones, ice, cork and sponges into a jar to raise the water for a thirsty crow, over eight levels, and the objects behave differently enough that picking the right one is the puzzle.
One game brings in an opponent: a version of dots and boxes, the pen-and-paper game of claiming squares, played against an AI at three difficulty levels or a friend on the same device. The grid and pipe puzzles suit people who like to see a whole board before committing to a move. The physics games are looser and suit those who would rather try a line and watch what happens. Frames are a mix of portrait and landscape format.
