I read that if you get any s ranked in a game that you will receive a box, my fiance and i have been playing getting s ranks and not getting boxes. we have tried different champs thinking that it was champ sensitive and still have only received one, the first one.
EDIT i gained the box but the servers did not tell me i have gotten a box, and are you only allowed one box per day? or every s ranked, because its looking like we are only getting one per day
the next chest is available in ~6 days, click on your summoner profile, it shows many days until the next is available
I believe the grade of s-, s, and s+ give you a box once per day and getting the final rank after 5 on your champion leveling up will give a box as well.
I got mine yesterday, but I couldn't see my lp gains which bothered me. All in all, it's not bad. Got a tomb angel ward. I like it. Now when I say all the wards on the map are mine I can back it up because mine are all tomb angels.
It's one box per champion, per season. Four boxes max per month. So to get the full boxes for a year long season, you have to get a box on 48 champions, doing 4 of them every month. You also need three key fragments for a key for each of those boxes, so total 144 key fragments. You will probably be getting a key frag each time you get one of those boxes, so now you need 96 key frags. You get a key frag for getting an A or better (I think) so you can plan it out from there.
Tbh, I'm not sure why people are having trouble getting boxes etc. I played yesterday afternoon and got 3 S-ranks (two boxes and keys, then one with just a key because I already had a box on the champ). So I was able to open one of my four boxes per month already because of the three key frags.
