Just thought I'd raise awareness of this, as I only happened to stumble across it by chance today going through the boards - basically, FREE STUFF!
IP bonuses, skin sales, merchandise sales, icon, mystery champion/skin (depending on if you have all the champions or not), POOL PARTY MINIONS, IP weekend (up to +300%!) for parties (team of 2+), and.......**_Pooooool Partayyyy Mundo!_**
It's contributed to by every single 5 premade team that wins - _every single one **globally**_. Riot is really testing out the community spirit here, as we have to accumulate _at least _ 5 million points for the first reward, which sounds like a lot but will probably be achieved fairly quickly. The real test is _55 million points_ for Pool Party Mundo. We're always described as a bad community. Let's show ourselves what we got!
(And earn some cool stuff too ^^)
There's lots of talk about public rooms for quick 5 man teams, so if you're lonely, look down the comments and you can probably find a way to match yourselves with people and do your part to make our way to that 55 million! They said they'll update the points daily 9:00AM PST (you might have to look up the time for your area) to show our progress, and the whole thing starts with patch 5.12, which I presume is soon ^^
All details are in the link, there's some stuff about connecting to Facebook and not receiving awards if you've had poor behavior recently (from February), but other than that;
**GOOD LUCK ON THE FIELDS OF JUSTICE!**
