Solved examples

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.

For example, let's take a look at this solution.

John
Molly
Shirley
Brian
Jenny
Harry

By rotating the circle to the left we obtain a similar solution, which is just as exact as the first.

Molly
Shirley
Harry
John
Brian
Jenny

By turning over the circle in a symmetrical manner, the solution is still as exact as the first two.

Harry
Shirley
Molly
Jenny
Brian
John

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.
