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.

Stages

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.
