Firstly I will advice to aviod surveys for earning tokens.
Secondly You can't ask a developer of game regarding spending tokens for better game experience.
Thirdly,You have read terms and condition of this game?
Forthly,This is not cheating,if you want to be better than others you need either money or talent.

Lets take this example,
Suppose you go to coffee shop.You was having few money so,You order a moderate coffee.When you demanded bill,you opted to be luck customer of day.So you got sip one more expensive cup of coffee.

Conclusion-Without money or tokens you have to lead simple team,It depend on your luck and talent to solve money or token problem.
Good luck.
