- Here is a solitaire game I invented to avoid learning High School algebra.
- It requires pencil and paper. Make an even number of vertical bars, thus:
-
- ||||||||||
-
- Connect pairs of them by arcs across the top of the array until each bar
- has exactly one arc touching its top end. The challenge is to connect the
- bars by arcs at their bottom ends so that the entire picture forms one
- continuous (but self-intersecting) line.
-
- After a little practice, you'll find an algorithm. But if the number of
- bars is large, finding a solution is still pleasingly difficult, at least
- if your standards are low because you're stuck at an airport layover. You
- can increase the interest by making a few random arcs on the bottom side
- of the array and trying to discover whether a solution is still possible.
