Winning at Wimbledon

As a result of temporary magical powers, you have made it to the Wimbledon finals and are playing Roger Federer for all the marbles. However, your powers cannot last the whole match. What score do you want it to be when they disappear, to maximize your chances of hanging on for a win?

It sounds obvious that you should ask to be ahead two sets to love (it takes 3 out of 5 sets to win
the men’s), and in the third set, ahead 5-0 in games and 40-love in the sixth game. (Probably you
want to be serving, but if your serve is like mine, you might prefer Roger to be serving the sixth
game down 0-40 so that you can pray for a double fault.)

Not so fast! These solutions give you essentially 3 chances to get lucky and win, but you can
get six chances—with three services by you and three by Roger. You still want to be up two sets
to none, but let the game score be 6-6 in the third set and 6-0—in your favor, of course—in the

Petals Around the Rose

Here are five rolls of dice, with their score.

Roll #1 – Score: 6

Roll #2 – Score: 4

Roll #3 – Score: 4

Roll #4 – Score: 8

Roll #5: 0

This is what you know:

1. The name of this game is significant (Petals Around the Rose)
2. The answer is always even

How is the score determined?

The solution is to count the dots (petals) surrounding the center dot (the rose).

Only odd numbers have a center dot, so even numbers (2, 4 and 6) are worth zero.

1 doesn’t have any surrounding dots, so it too is worth zero.

The three has two dots surrounding the center, so it’s worth two.

A five has four petals around the rose making it worth four.

The Greatest God

The Pharoah asked, “Who is the greatest god?”

“I am not,” said Horus.
“Anubis is,” said Isis.
“Isis is lying,” said Anubis.

Only one god was telling the truth and the other two were lying.

Who really is the greatest god?

Horus is the greatest

“I am not,” said Horus = LIE
“Anubis is,” said Isis = LIE
“Isis is lying,” said Anubis = TRUE
