CyBall uses an energy system in which the player must spend part of their 60 daily Energy to join a match. Missing Energy is replenished at the start of each day, using UTC+0 as the base timezone (subject to change).
Example:
Exhibition 3v3 matches cost 3 Energy and should last roughly 5 minutes on average.
3 Energy/match = 20 matches/day ~ 100 min (or 1.7 hr) of gameplay/day.
