what does tilted mean?

It's a poker term that is applicable to chess playing. It's a state of extreme frustration that is likely to lead to making poor decisions.

Tilt is your emotions interfering with your rational decision making.

Tilt is not as bad as people say it is. When I keep losing and my rating is experiencing free fall, I like to keep pushing the games even harder so that the tilt leads into a small emotional explosion. Once I am done releasing my high adrenaline levels, I feel much better. Only my keyboard usually requires replacing

Move or cause to move into a sloping position. I hope that helps.

I looked into it and I believe that I stand corrected.

Did you find evidence that it came into chess directly from pinball? I find it hard to believe.

After looking into the etymology of the word tilt, I do believe that the term originated from pinball. Determining how "tilt" came into chess is practically impossible to prove.

I bet that they use it in pinball in a quite literal way, for the machine and not for the player.

The figurative way it is used in chess was already used in poker 50 years ago, probably more.

So I guess you were right in the beginning, it came to chess from poker.

its when you get extremely frustrated and generally lose quite a lot of writing due to this. This loss in rating will cause you to get even more annoyed and you begin to get into this cycle.

Just throwing this here without any explanation isn't going to help anyone. It is pretty impossible to figure out how they use the word figuratively in pinball, even using google.
