How does a serial protected computer game determine which serials are valid and which aren’t?

For example, let’s say you own two legal copies of a video game, both with different serials. If you installed the game, it wouldn’t matter which serial you used because they’re both legal. How does the game know the difference between the valid codes or you just typing a bunch of random numbers and letters?

it uses a binary code to disifer right codes from wrong codes

The game either has a library or formula to determine if your serial is valid. For instance, if your key was 3FTY6P0, the formula may check if there is a letter in 2nd,3rd,4th,6th and 7th postions. Perhaps a 3 and an F generate a 0 at the end. Newer games may consult a server, but most likely they rely on a formula to recognize a valid serial. A serial generator has found the formula, then goes backwards, using the formula to construct a key that will be accepted by the program.

I believe that they use a certain algorithm to determine “Legal” keys…. something like this character is a letter…. next character is a number from 1-6 unless first character was F-M, 7-0 if first char was R-U, otherwise its a letter from W-Z…. etc….
I could be wrong, but it should be something along those lines…
