Temple Run/Gameplay

Objectives
Objectives are unlocked by performing certain actions during a run or by buying things in the store. Each objective you unlock adds to your score multiplier, making higher scores more easily attained the more objectives you earn. Objectives are unlocked at the runs, so even the store purchase objectives require you to at least complete one more run to obtain. At the end of runs you will be notified of any objectives you have obtained along with an update to your score multiplier and a notice of the next unobtained objective in the list.

Score
The object is to survive, while also getting the most points and coins possible. The longer you survive, the more points you acquire, and your score can be used to unlock objectives. Your score is determined by the points you earn and your multiplier. You earn points by running farther and collecting coins and powerups.

You get:
 * 1 point per meter
 * 5 points per coin
 * 25 points per powerup

Coins come in yellow, red and blue, worth 1, 2 and 3 points respectively. Coins appear in lines along the path in the center or to one of the sides and each line usually contains 25 coins if not broken by a turn in the path or an obstacle. The red and blue coins will start appearing the farther you run and are evenly interspersed into the coin lines. When you get to the reds, they replace ten of the normal coins and when you get to the blues, they replace another ten of the yellow ones.

You also earn points by filling up the bonus meter in the upper left corner each time you collect 100 coins. The circle at the top of the meter starts out empty, and every time you fill the meter a piece is added until all three pieces are in place. The first piece is worth is 100 points, the second is worth 250 points and the last is worth 500 points. Every time you fill the meter when the circle is full, you will get an additional 500 points. Stumbling or resurrecting will cause the bonus meter to reset, in which case you must earn all three pieces again.

Finally, your multiplier is applied to every point you earn. You start the game with a 10× multiplier and each objective you earn increases your multiplier by 1, so you can have a maximum multiplier of 67× after completing all the objectives.

In addition, you can boost your coins earned (and thereby your score) with the Coin Magnet powerup, which allows you to collect more coins and multiplies their value by 2× or 3× depending on how much you upgrade it. To score well, try to complete as many of the objectives as possible as early as possible, as they have the biggest impact on your score. After that, the Coin Magnet and Coin Value powerups will help the most, as will buying a lot of Resurrect utilities to keep your run going.
