What are Keys used for in the game?
Keys are used for opening the crates that you can access at the end of each beaten level or by tapping the Key icon at the bottom of the main game screen.
You can find more Meteormites, Diamonds, Energy and Fiends in the crates!
Where do I find the Keys?
In the world map levels you’ll receive 3 Keys for beating a previously unbeaten level, 1 Key for previously unbeaten levels in the HERO World Tour and you’ll also be able to collect Keys from within the levels, too.
You can win Keys for reaching levels 10 and 20 in the Fiend quest levels.
We also have daily special events where Keys are part of the reward for completing! Check out the daily events and the Earthworm events! We also have extra challenges introduced with each new update!
