I would like to know about this also. Thanks!
me three! why is it ticking down time? what am i going to miss out on because i dont know what it is or how it is used??
This info is actually out there in the FAQ's, which I didn't know for months after playing.
Every time you see a treasure chest with an !, click on it. It will take you to the right one. Click on it, and it will send rewards to your Home button. You may get coins or necessary requirements to upgrade your good characters.
The time limit is for when the next available reward is available.
Make sure you go through EVERY page to see if there is an ! by a treasure chest. If you play long enough, you will earn more, as each chest has different timing. The longer the timing, the better the reward.
To see what your good characters need, go to Home to check. I learned this the hard way, but it works. :)
Good luck.
The timer is just to let you know when the chest will be able to be opened again.
Don't know about the rest.
My treasure chest has an ! but I can't open it!
After I have upgraded my good guys, how can I use the items that come from the treasure chests?
