  1. Several people are in a circle. Your aim is to place each person by using different clues. You can be told whether people are neighbours or not (e.g. "Jack is next to Leo" ), and whether or not they are face to face (e.g. "Harry is in front of Jane" or "Harry isn't facing Jane"). This game allows symmetrical awnsers, and it is important to take them into consideration.
  2.  
  3. For example, let's take a look at this solution.
  4.  
  5. John
  6. Molly
  7. Shirley
  8. Brian
  9. Jenny
  10. Harry
  11.  
  12. By rotating the circle to the left we obtain a similar solution, which is just as exact as the first.
  13.  
  14. Molly
  15. Shirley
  16. Harry
  17. John
  18. Brian
  19. Jenny
  20.  
  21. By turning over the circle in a symmetrical manner, the solution is still as exact as the first two.
  22.  
  23. Harry
  24. Shirley
  25. Molly
  26. Jenny
  27. Brian
  28. John
  29.  
  30. To sum up what we've just said, a circle of 6 people allows 12 possible solutions. So use this help, and don't ask yourself useless questions : only face to face, and side by side relations are important.
