You may have seen this puzzle where you have to connect 9 dots with 4 straight lines without lifting the pen from the paper or going back on yourself — it’s a traditional ‘thinking outside the box’ puzzle. The solution is at the end of this article. If you can do the 4-line solution, try it with 3 or even 1 line! See below.

Variations

  • 9 dots, 3 lines

  • 9 dots, 1 line

If you get bored with 9 dots, try:

  • 16 dots, 6 lines

  • 25 dots, 8 lines
