Cheat Engine

[PsychicSymphony]

Ok soo im getting into cheat engine and I decided I will make a solitaire trainer. I started making it found the score address then began to look for the static pointer. When I found it it was one of them that started with FF which all the others started with like 00(do all static addresses look like this?).
so I took it added it in to the cheat table by typing in the address and the offset was 000000F8. When I added it in and changed the op code to what I wanted it worked. But when I restarted the program the static address changed I was all "wtf?!"

green ones<- I think there called static addresses.

Is it normal do static addresses change or is this just me.
