An old phone can still fight a round

Yes, as long as the browser still gets updates. Nothing here loads video, nothing uses heavy effects, and each game is tried on a weak device before it joins the list. If the first second stutters, wait about ten seconds before judging.

Usually two to five minutes; that is the selection rule for this site. Games with longer matches, or that punish you for stopping early, are left out, because the point here is to finish a round and be able to stop.

No. Every game opens straight in the browser and never asks for a name, an email or a password. Any page demanding registration is not part of this list.

Little. The page loads once and a match afterwards sends only small messages. Avoid closing and reopening the tab, since the first download is the expensive part. The guide on data in the notes section explains the details.

A game that blocks the door with a long advert is removed from the list. A few may show a short one after a match ends, but none makes you sit through a waiting screen before you can touch the arena.
