A lot of people who hasn't figured it out yet, so i decided to make a tutorial instead (if you're a achievement collector). You know when you buy the mobile ad in the tab section? You can actually interact with it and literally plays in the game, you have to beat Level 1 in order for you to achieve the "Real gamer" badge. The rest of the badges well, you just have to get them 100 times on each item or buy everything in the store.
