What are the 8 rules for 8 Mask patterns for QR code?

I was making some QR code manually and I'm stuck in the Data Masking part of making the QR code.

The section where I became confused is underlined as shown in the picture below, saying that there are 8 rules for each masking pattern for QR code.

enter image description here

The website where I read the Data Making pattern is here:

https://www.thonky.com/qr-code-tutorial/data-masking

The rules to create the first and second masking pattern for a QR code has been stated, namely:

For mask pattern #1, every even - numbered row in the QR matrix is masked.

For mask pattern #2, every third column in the QR matrix is masked.

The third to eighth masking patterns weren't stated and I wasn't able to find it when googled. The rules are applicable to particular masking pattern and there were eight rules, so there are eight masking pattern to be created.

My question is:

What are the 8 rules for 8 Mask patterns for QR code?

Thank you for helping me out!
