dword is commonly used everywhere, from "cash" to "points."
It's a 4byte integer (unsigned), with the maximum value of (in numerals) 2,147,483,647.
If you have cheat engine, you can see the default data type is in "Integer" or "4 byte". It's pretty much the same/similiar to DWORD.
Although, there's binary typed DWORD but I don't want to give some long ass explanation.
