What are the numbers off to side for on mastermind board game?

The numbers off to the side on a Mastermind board are for keeping track of the number of guesses you've made.

Here's how it works:

* Each row represents a guess.

* The numbers on the side increase sequentially. So, the first row might have a "1" next to it, the second row a "2", and so on.

* This helps you stay organized and know how many attempts you have left.

The numbers themselves don't have any other gameplay significance. They're purely for reference.
