Puzzle: A game of avoiding the neighbours
The game is to use the consecutive series 1-to-8 and enter one number into each circle in such a way that no two numbers adjacent to each other in the natural serial order (1 2 3 4 5 6 7 8) occupy circles directly joined by one of the straight lines. For example, if 4 is in the far left circle, neither 3 nor 5 may be positioned in the column to the right of it.
