Hi, how can we help you?

How do I become strong?

Why can I not see advertisements sometimes?

How can I obtain more towers and heroes?

If I've switched devices, can I still use my original account?

How can I bind and switch accounts? How do I change my password?

What do I do if my game top up isn't showing up in my account?

Why is the top up sum changeable?

Please refrain from using any non-official methods of payment

What's the difference between Upgrade, Ascent and Increasing points?

In battle mode, why is it sometimes particularly fast and sometimes particularly slow?

Why does the same boss sometimes have really high HP and sometimes really low HP?
