From time to time we get questions on how we chose weekly free champions. We rotate the Champions to keep the game fresh for those that haven't unlocked all the Champions.
Here is how we choose which ones are free:
Champion Rotation Goals
1) Give new players some simple Champions to play
2) Provide a balance of types of Champions for new players
-- This allows new players to make balanced teams
3) Allow players to preview all Champions eventually
Given these goals we look at player feedback, and decide which Champions should be free next week that allow us to meet these goals.

Frequently Asked Questions:
Q Will new Champions always be free the first week?
A No, we will debut Champions that need to be unlocked, but eventually they will be free (see goal 3).
Q Will some Champions be free more often than others?
A Yes, because some Champions are simpler to play that others, and our first goal with the free Champion rotation is to allow new players simple Champions to try for their first games.
Q I don't think Alistar is a Tank
A Okay - not a question, but yes, thanks to our item system, Champions can be built different ways. That means many Champions can be played as different types (for example, as a Tank or Melee DPS). To keep things simple, we list only one type for each Champion in our statistics, but many of them can be played differently than the type we list.
Q Do the Champions rotate on the same day every week?
A No. We often synch the Champion rotation with the new content and patches we are releasing. Because we won't release the patches until they are done, this means they sometimes don't fall on the same day each week. This leads us to rotate our Champions on different days of the week to try and get even amounts of time between Champion rotations. This is also why we don't announce the exact date of the rotation.
I'll link to this post from the Champion rotation announcements to answer the questions that keep coming up. If there are more frequently asked questions, I'll post the answers here.
Thanks for all the requests for free Champions!
