Game keys in theory

So. lets say regular game key consists form XXXXX-XXXXX-XXXXX.
every X can be number (0-9) 10 number overrall or latter(A-B) 26 different latters. no small latters
So every X got 36 different possabilities.

So there is 36^15=221073919720733357899776 different keys in existence.
If you try to guess a different key very 10 seconds you will need 67691161976023098,514285714285714 or
approx ~67691161976023099 years.
So in THEORY all you beggars, dont waste your time ! go and start guessing and
in near future you will get your key!
