# Is there any solution of this game?

There is 5 number.
7 7 9 5 7

If you click one number then this number will add with one(+1), and subtract one(-1) with others.

For example, if I click 5 it will be like,

1nd click ==> 6 6 8 6 6

If I click, most right number 6 it will be like,

2nd click ==> 5 5 7 5 7

and so on.

I can click just 7 times.
Is that possible to make it just 1 left? If it is, then how?

Expection after 7 click,

0 0 1 0 0

or

1 0 0 0 0

and so on.

I don’t understand the rules

but what do you need to do, write an algorithm for it?

Here are those numbers,
7 7 9 5 7
Imagine you are a robot. What you can do is just a simple calculation at most 7 times. In each calculation, you will target one specific number among 7 7 9 5 7.
Each time, 1 will be added to your targeted number, and 1 will be subtracted from other numbers.

For example, if you target 5 in your 1st attempt then, 5 will be 6, and 1 will be subtracted from others. So, it will be,
6 6 8 6 6
You just have 6 attempts left, to make it 4 zeros and 1 one.(It can be, 0 0 1 0 0).

So, according to rules, Is that possible to make those numbers(7 7 9 5 7) to 4 zeros and 1 one phase inside 7 attempts?
Hope it helps And about the algorithm, is that possible? Because those numbers (7 7 9 5 7) and the number of calculation-time(7) are constant.

How would that be possible though?

If you click on a number and it adds 1, and you click it 7 times then it would be 16. Right?
How can you get down to 1 when you started at 9?

Also, for this 5 here,

it wouldn’t go down to zero it would be -2 if you clicked the number 9 7 times.

Did I understand the rules right?

Sorry, I forget to mention. If any number is 0 then subtraction will not apply. But, addition will be applicable according to rules.

It doesn’t matter, if 9 is one of the numbers it’s impossible, the lowest it can get to is 2

I’m sorry, I’m the real fool  I tried to pre-register there. It asked me 8 questions within 30 minutes and it was one of them. Maybe it was April fool Here is my result, This topic was automatically closed 182 days after the last reply. New replies are no longer allowed.
