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.

Just for clarity, it helps to name the leftmost e "e1" and the rightmost "e2".

The p and the e cannot move. This leaves r-blank and a-x. a-x would solve nothing, so move r-blank, and keep moving it to e1. Now move a-x, which allows e2-u-r. Move e1 back to s, and x-a, which allow p-l-P. Move a-x again, and then s-e1, and r-blank.

Sorry-this is wrong. Currently revising :(
