I tried the other machines when I wasn't hitting anything, but looked at other threads and did what others did - stuck with the first machine the Dorothy and Toto. I don't know if it's luck, but as I said, I just did autospin and looked up every few minutes to clear screens if needed. $50 bucks (well roughly $45 with what I bought in game), to let autospin and do nothing really except check the game a few times To me worth the current deal of 1000 swagbucks bonus plus the 4000 swagbucks to hit level 101.
I did buy two $1.99 packages when I ran out of money ( I think I ran up to level 67 FAST, and then it stuck or I kept running out of money - so I bought the deal they had). I hope others try, it felt like FREE MONEY! Want to jump in and say this was the easiest game I've ever played on Swagbucks.
