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.
If you can do the 4-line solution, you may be interested in trying it with 3 lines.
I'll be posting the 1-line version next week.
This puzzle is part of my collection of icebreakers, exercises and puzzles which can be found on LearningPages.org
Solution
This drawing shows the 3-line solution (this only works if the dots are not points).
