I tried to grind the fun steps a little bit, they are pretty aggravating.
Fun Step 1: 3 out of 10 players move on to fun step 2.
Fun Step 2: 2 out of 10 players move on to fun step 3.
Fun Step 3: 1 out of 10 players win $1.
Using just the percentages, (30% x 20% x 10%), when you are holding a Fun Step 1 ticket, that puts your chances to turn it all the way into winning the Fun Step 3 and win $1 at 0.6%.
I do realize that your skills etc can vary your winning percentages. For example, fun step 1 is filled with terrible players, and I've found that my fun step 1 winning percentage is closer to 50%-60%, as opposed to 30%.
The point I'm trying to make is, it's a lot of time and definitely not worth it.
