Temple Run 2

These achievements are tied to the objectives for scoring 25,000 and 1,000,000 million points in a single run. See "The Spartan" for more information on objectives. Points in the game are earned for a variety of things and the formula is actually quite complicated (check it out HERE). Obviously the further you get the more points you get, but collecting coins and power-ups is also important. Additionally completing objectives will increase you base multiplier for all subsequent runs. This basically means that initially it will be hard to reach, say one million points. After you get some objectives completed, it will be quite easy, even though the game is the same, due to the way the formula changes. You can use as many Save Me continues as you want (if you have the gems to do so).

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.
