one stroke draw - 一筆描きパズルゲーム

A puzzle game that anyone can play, connecting lines with a single stroke!
I have a lot of free time, but I don’t have any money... Is there any interesting game that I can play to kill time for a long time?

I would like to recommend this game to you!

First of all, let me introduce the rules of the puzzle.
This puzzle game is played by connecting dots with a single stroke.
Once a line is drawn, it cannot be passed twice, but the dots can be passed as many times as you like.
There are many stages, but there may be more than one way to clear the puzzle! Use your own ideas to clear the puzzle!
If you have a flash of an idea, you can clear a stage in about 10 seconds.

This is a game that you can enjoy in your spare time. It is a brain training puzzle that tests your imagination and IQ rather than your knowledge because it is a game where you draw and test your ideas!
You may find yourself playing for several hours, so be careful not to get too addicted!
If you have some free time, please give it a try! You will enjoy it!
