Place four coins on the bottom row of circles (p a e r) so that the word "Plexus" is showing.

Your aim is to slide the coins along the lines from one circle to another (no stopping half way!) to expose the word "pleaser" (noting that there is a difference between the capital 'P' and the small 'p'). There is only one catch: At no time are two coins allowed to be next to each other along a line.

So for instance, the coin on 'p' cannot move initially, or it would end up next to the coin on 'a'. Some of the lines are easily missed: note especially the u-r connection.
