1 line is a free-to-play puzzle game, you merely have to draw one line. It is deceptively simple, yet profoundly deep.
Play through the extensive stages, sharpening your wits as you have fun.

A brain-training puzzle game that activates your mind as you play.
When you've got a spare moment, on your daily commute, or before going to bed, why not experience what it feels like to activate your mind?

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 a large number of stages.

When you get stuck, make use of a hint.

There are 6 levels and a total of 300 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.
