Puzzles and Curious Problems by Henry Ernest Dudeney: $333$
- A Hopscotch Puzzle
- We saw some boys playing hopscotch, and wondered whether the figure marked on the ground could be drawn in one continuous stroke.
- Can the reader draw it without taking the pencil off the paper or going over the same line twice?
Solution
- It is necessary to start at $A$ and end at $B$, or start at $B$ and end at $A$, otherwise it can't be done.
