Yea on carbon, i managed toget a free dolar with the fun step games, played with that 1$ for about a month breaking even and coming up some, then finaly lost 10 games in a row, the downswings are rough, the upswings do not come as often as you would hope for.
If your serous about thos ST games i recommend a huge BR bc the swings WILL be crazy, but its good for getting rake, and getting more points faster. Just know your AA will get beat more and you will suck out just as badly. IF your trying to make money off this in the long run, your cant NOT let the bad runs get you down.
I do not recomend these bc phsycologically it is stressful unless you are running like a beast, but gl to ya
