What it does to your session
Written once for this mechanic, not per title.
Lengthens sessions by design, and is worth flagging in a responsible play context even where it is not a regulated feature.
Also called
The names other studios and other sites use for the same thing.
Meter Fill · Progress Bar · Charge Up · Collect Feature
These resolve to this one entry. A studio’s trademark for a mechanic does not create a second mechanic, which is why a search for any of these names lands here.
