A brain-training puzzle game that activates your mind as you play.

How to play:
There is only one rule:
"Connect all the points with just one line."
It doesn't matter where you start.
There are some fiendishly tricky, complicated puzzles among the large number of stages.
When you get stuck, make use of a hint.
There are 15 levels, and a total of 850 stages.
At first, it starts off with simple shapes, but each time your level increases, the number of lines increases, and it gets more and more complicated.
You might think it's too easy early on.
However, clearing the simple stages is also important.
The hints to clearing the later, more complicated stages can all be found scattered through the simple stages.
Some unique types of line, such as "one way lines" and "overlapping lines", can also be found throughout the stages.
These special lines will encourage your imagination.
Use this chance to activate your mind as you play, by trying to solve this free-to-play brain-training puzzle game.

Where to start and finish, and bridges
Kudos to authors for monetizing some very basic graph theory (the topic here is Eulerian circuits and Eulerian trails). Check how many edges sticks out of each vertex. That’s called the “degree” of a vertex. If all vertices have even degrees, then choose any vertex as both your start and finish. If exactly 2 vertices have odd degrees, then those 2 vertices are your start and finish. In that second case (different start and finish), pay attention to vertices and edges called “bridges”. Those are vertices and edges which *must* be on *any* path from the start to the finish, whether it contains all edges or not, they’re *unavoidable* in getting from here to there. Mentally take away those edges and cut these vertices in half, and you’ll have some “islands” (those are called “blocks”). Make sure you use up every edge of each island before you cross the bridge to the next island. Oh, and double edges (they’re dotted) count twice, etc.
Don’t waste your money buying “ad free” - there’s still ads...
Really fun addicting game. I was enjoying it so much that I decided to go ahead and buy the paid version of the game to remove the ads. I was really enjoying the game without the little pop ups on the bottom or between levels, but found that once I finished about five levels, an ad would pop up right over the “continue” button to watch a video and get a free hint. I have hit that pop up on accident so many times because of its short delay and being right over the button I’m trying to press that I have gotten very frustrated. When I paid to remove the ads, I wanted them ALL gone. A pop up to view an ad is just as bad as an ad itself, especially when it tricks you into clicking on it. Then you have to navigate back to your level and the meditative state from focusing on the game gets totally ruined. The game is good if you don’t mind ads, but DONT WASTE YOUR MONEY trying to get rid of them. That pop up to watch a video after every few levels will alway still be there. Very disappointing. WOULD NOT PURCHASE AGAIN
THIS IS THE BEST GAME EVER BUT CHALLENGING 😛
I love this game for many reasons well I should tell you those reasons because it is challenging but not to hard because I love challenging games but not to challenging but this is perfect I also like it because it gives me hints and I don’t have to buy them with money another reasons is when I ask for a hint then it gives me 1,2,3 and then if I get the shape wrong and then I start over then it still says 1,2,3 so I don’t forget where they where because I think I forget a lot and I also think I have memory problems but my mom says and I quote “ no honey you are fine “ but you know I love this game and it is the best game to play on the airplane or in the car or just when you are waiting or you are bored so if you are looking for a fun, challenging, creative game then this is the game that you should get😜.
