Possible solutions:

* Cycles run on a 6 day, 23 hour clock. Pro: an end time convenient for everyone eventually comes around. Con: most benefits people with no life.

* Random end times that are at a prime hour for majority users.

* Divisions based on time zone that’ll roughly distribute the community (mentioned above I believe).

* Make being available near the end time less significant, such as limiting the number of cards that can be played in a day.

I like the last one for sure, coupled with one of the above. What do you guys think? I definitely don’t like the same end time every week.
