Which map is the most efficient for coins and gems in Temple Run 2

Which of the three maps:

1.original Sky Summit

2.next Frozen Shadows

3.current Blazing Sands

is the most efficient for collecting coins and gems for a fixed amount of time playing?

They all seem to have pluses and minuses in terms of efficiency per time and distance but I am wondering if anyone who plays a lot has already done experiments before I try some of my own.


Solution 1:

Sky summit gives constant coins and diamonds. Blazing sands is more difficult but seems to give preferably one type of item per game: more gems or more powerups or chests. It is however more fun and you get hints about your next turn, if you pay attention. Good luck!
