The road ahead is long and hard lol but worth it. It took me 2yrs plus a chunk of money to get a free premium game. Pretty much everything said above is the route to go to get things rolling. You want to build your percentage multiplier. And when you have it available try out using the XP collider. You will be farming XP for donuts. To farm xp you want to build and harvest kwik e marts. But only make the xp collider investment when you can already gain a fair bit of cash and xp. And the best bang for your donuts is the mystery box. You want to pull out the news vans (2%) and the itchy and scratchy billboard (1%) to build your multiplier.
