A “Sudoku Shopping Center” was recently opened in Timbuktu, where Sudoku addicts could go and choose a puzzle from among many. It was spread over five floors, and the puzzles increased in difficulty levels as you ascended. The only rule was that once you open the door to any floor, you HAD to choose a puzzle from that floor; if you went up one floor, you could only go down to leave the place, never to return.
A couple of women addicted to Sudoku went to the mall to find some puzzles …
First floor. The door had a sign that said, “These puzzles are for kids.”
The women read the sign and said, “Well that’s better than not having any puzzles, but I wonder what lies ahead.” So they went up.
Second floor. The sign read, “These puzzles are specially designed for seniors.” Hmmm, the ladies said. But I wonder what is higher up.
Third floor. This sign read: “These puzzles are very challenging and would need a good player to try to solve them.” Wow! the women said. Very tempting BUT, there is more up above! And they went up.
Fourth floor. This door had a sign that read: “These puzzles are BAD and almost impossible to solve without help. If you can solve them, you are a certified genius.”
“Oh mercy me. But just think! What must be waiting for us later!”
So they went up to the fifth floor.
Fifth floor. The sign on that door read: “This floor is empty and exists only to show that women are impossible to please!”
