In the 1960s, Dr. Nim took the world by storm as a popular single-player game. NOW, Dr. Nim is taking the World by FORCE as a rogue artificial intelligence, seeking out and eliminating anyone who managed to beat it in the 20th Century.

Use an RPG.

Pleeeaase, state the bonus riddles better! Am I allowed to choose a single square? It looks like all rectangles must stretch to the top right as much as possible, is that correct?

I just realized – this is like a very simplified version of the actual game NIM!

What about throwing remote control at the button?

Since I haven't seen anyone mentioning the solution that I get, so here is what I get.

I tried using equation x+3y+4z=25 to start with. To win, the sum of x+y+z must be an odd number (since your turn is odd).

However since 4 is an even number, and an even number times anything is an even number, then x+3y must be an odd number. (x+3y+4z=25<- odd)

We can split x+3y = x+y+2y

2y is an even number, thus x+y must be odd.

To win, x+y+z = odd number, and x+y = odd. That means your only chance to win is if z is even.

Thus, whatever you do, as long as 4 is selected an even times, you will always win.

Me: (Lowers water to level 21) Okay, NIM, it's your move. (Long pause as nothing happens) Uh, NIM?

NIM: I calculated that whoever makes the next move will lose, so I'm not going to do anything.

the correct answer:

don't make nim

In my school we learnt this in the Fibonacci sequence

Solution

If you fail just get back in it’s not like in 3 seconds the world will end because of that

You have hours so just hop back in and use the raft as a safe bouncy surface and turn it off

Why don’t you just tell the military to obliterate the thing? 😂
