Why is mind reading so accurate?

Haha, you don't have to look at it to know that this is a small game.

I was surprised to meet you before.

Later, after five minutes of research, the mystery was revealed.

This is a very simple math game. Look at the following calculation formula:

( 10X+Y)-(X+Y)=9X

In other words, according to the original algorithm, the result must be a multiple of 9, so let's look at the icon again. As long as all multiples of 9 are the same icon, hehe, so no matter what numbers are in your mind, you must have clicked the same icon.

And every time you restart the game, the screen changes, giving you the feeling that the symbols are different every time.

I saw it. It's not the same as the one I met, but the principle is absolutely the same.

Test method: after you see the picture, you can see what the symbol of multiple of 9 is, and then you don't have to worry about attention or anything. You can directly see if the answer is a multiple of 9.

Numbers exceeding 8 1 are inaccurate because if we really calculate according to his method, we should not get numbers beyond this range, that is, it is impossible to get numbers exceeding 8 1, so just stare at 63!
