Embers

Embers are the points needed to construct the values engine. More embers means you can create values engine of higher level. Higher level of values engine means high value flow rate which will make gems production fast.

You can get 50 embers while signing up as an new user. Level 1 values engine can be created with just one ember. But to create level 2 values engine you need to have 60 embers which won't be possible unless you collect the chests.

It will costs 600 embers for creating level 3 values engine and so on.
