In ancient days gone by a wealthy land owner challenges his two sons to a horse race.
The one whose horse is slowest will inherit the entire estate.
After a few days into the race, the brothers have made no progress and begin to wonder what to do.
Upon the advice of a wise old man they jumped on the horses and raced as fast as they could to the finish line.
What did the wise old man suggest?
Hint: Think laterally.
The wise man told them to switch horses as the race depended on the slowest horse.
This chess King has to visit every square on the 5x5 board, once, and once only.
However, this King can only move up/down or left/right, and cannot move diagonally.
How can the King complete this challenge?
Hint: Try moving the king around in your head.
Answer: This cannot be done, no matter what route the King takes, there will always be at least one square unvisited.
