Pin (1985)

A simple abstract solitaire game (players can compete by taking the same setup and trying to outscore the other). 20 pegs ('pins') of five different colors are placed on a square 7x7 board. The game contains two white pins which are connected by a string - the first white pin is placed on the board with the starters. The player's challenge is to place the 2nd white pin on the board, looping the string around as many pins as possible, each color pin being a different value. The string must change direction at each pin, and the 2nd white pin must be placed so that the string is taut. A unique and challenging puzzle for one or two.
