temple run 2 gold color circles

Solution 1:

If you are referring to the gold disks that float in the air that you need to jump for, those are a coin power up. They don't give any immediate bonus to your performance (unlike the magnet, shield, or boost powerups) but they are useful in that they can fill your bonus meter quickly. Such a successful jump and grab moves the bonus meter up about the same as multiple sets of low-level coins. Once the bonus meter is full, you can use your own power up of choice (shield in the illustrated example above, but boost and the Usain bolt ones tend to me more popular if they are available) sooner than if you didn't jump for that disk. It's not worth jumping for such a disk if it means you'll land in a gap and die or have a stumble or difficult move to stay alive, but frequent use of the powerups from the bonus meter is important to doing well in the game.
