I don't think you are legitimately that high lol. If you took some tests most are so inflated it's not funny.
But yeah this game weekly links to IQ for a series of reasons:
*How much knowledge you possess on the game specifically
*How much effort you make
*How well you are on verbal
*Strategizing which is not merely about IQ, but also looking into the future, tests do not measure that
I could go on.
If you took Magnus Carlsen vs. Stephen Hawking in a chess battle Magnus would have likely won very very swiftly.
