Merge Games such as Merge Nymphs

[DarkDaemon]

I've gotten a good understanding of the basics of game guardian however there's a hack id like to figure out or know how to do. If someone can assist me id greatly appreciate it in most of these merge games they allow you to merge 3 objects of a low tier and then get 1 object that is a tier higher and offer option to merge 5 low tier objects and get 2 objects of a higher tier. What I'm wanting to find out is how to find the value the determine the 5 to 2 merge and change it to something else such as 5 to 5.
