# Real Mathematics – Game #5

Me versus You

I am going to play a game against you. Yes, I am talking to you, my beloved reader. I promise you that I will personally hand it to you whatever you win at the end of the game.

Rules:

• You will start the game from top-left box. You will be making mini-runs. In other words you will take as many steps as I tell you to.
• Each time you can take a step towards one of these four directions: Up, down, left and right.

• As long as you follow the second rule you can move freely. It is allowed to visit the same box more than once. Also you can go backwards too.
• You should start your next step wherever you stopped in the previous run.
• After every run I will select a box or two and eliminate them from the game. In case I eliminate a box where you are currently sitting, you will be declared as winners.
• I repeat: Your steps should be either of these directions: up-down-right-left.

We’ll start whenever you are ready. Good luck.

Game

1.You will be moving inside these 9 boxes starting from the top-left which is the 1000-Euro box. Take 5 steps.

2. I know that you didn’t stop at the 1000-Euro box. So I am eliminating it. Now, wherever you stopped in the previous run, start taking 7 steps. Did you do it? Okay, you can go to the next.

3. After those steps I am 100% certain that you didn’t stop at the 1000-dollar box. Thus I am eliminating it. Now continue the game with taking 11 more steps.

4. This time I will make a bold decision and eliminate two boxes: Left-bottom corner (a bag of money box) and car key box. You are sitting either one of the following five boxes. Now take 5 more steps.

5. I know that you are not standing on the Iphone box. I also know that you are not on the 100-dollar box. After eliminating them, take 1 last step from wherever you are standing.

Result: Now I can eliminate Starbucks coffee and 500-dollar boxes as you are standing on the zero box. I am afraid this is what you won: A big, fat zero.

One wonders…

You can play this game from top over and over again. In the end, you will get the same result. How is that possible? Why am I this confident?
