Facebook options

Connecting to Facebook not only allows you the ability to send your entertaining friends taunts and challenges but also gives you extra Gru tokens the first time you connect it, 50 to be exact. If you have a Facebook account, make sure you link it up.

If you don't have Facebook, you'll most likely spend a little more time collecting tokens in order to skip levels that require Facebook. You can either buy tokens or collect them during runs and by completing certain objectives. Once you've got a good stash of tokens, you can simply skip the tasks that require Facebook by paying a certain amount of tokens.

Don't forget to collect your rewards

As you complete tasks, Gru tokens will become available to you for doing so. Make sure you don't forget to claim them. Minion Rush is sneaky about not really explaining this.
In order to claim tokens for the achievements you've completed, tap on the Goals menu from the main screen. Along the top you'll need to toggle from the goals tab to the achievements tab. Scroll through the list and see if any are completed. If they are you'll see a claim button next to it
