Temple Run 2

All achievements in the game are tied to the objectives in the game. There are three objectives active at any given time and they can either be required to be completed in a single run, or can be cumulative across numerous runs. It depends on the specific objective. After you complete an objective, a new one will be given to you. Every achievement is tied to an objective, but not all objectives offer an achievement as a reward. Note than you cannot complete the requirements for an achievement before they are displayed as an objective (some you can but must complete a run after having it active). Completing objectives will earn you progress towards leveling up and also increase your score multiplier for the game.

See the individual achievements for tips for each specific objective. There is nothing to worry about missing as your progress through the game. 

This specific achievement is tied to the objective for scoring 1,000,000 points without using a single power-up. See "Million Club" for more information about scoring points. By the time this objective becomes active, you should be quite skilled at the game and have little trouble doing so without using power-ups. You must not collect any power-ups that you have to jump for and also not activate your permanent power-up that becomes available when you fill the power bar by double-tapping the screen. You can use as many Save Me continues as you want after dying (if you have the gems to do so). This will likely be your last achievement in the game. Gems and chests are okay to collect, but some have reported issues when collecting them, so it is probably best to avoid them as well.

See the Cheap Trick for the Tougher Achievements section at the end of the RoadMap for a very easy method to earn this achievement using no gems.
