Under rating threshold (hideshow)
The slot machine is only a waste of cash if you have a low amount. If you have any lower then 200, I wouldn't spend it on the slots. But if you have a lot of cash and don't know why to do with it, the slots are a good way to go. By a ton I mean 2-5 thousand. http://prntscr.com/751ka7 Like that would be considered a lot of cash. But, if you were going to buy on TDP4 I'd made a Darkness Project account since it's much cheaper then on Kongregate. You know what, nevermind, don't buy at all.

would be awesome if you get more money more EXP and sometimes on kongregate you will get free kreds like example 150 or something
