Is ARAM Champion Select Truly Random?

Yes, it is really random. You will see free champions more often because they're the only champions that everyone owns.

Random is just that: random. Humans attempt to find patterns where there are none, and wind up perceiving that maybe the randomness isn't really random. They're wrong.


True Random? No. Pseudo Random? Yes

It will be so random a Computer could do without other Tools. So the Core Answer: Yes the Hero Selection is Random and no Pre-Defined Set Of Heros or Algorithms which choose them for you. But i don't think it will be True Random.

I dont think so i got all champions, i play only in aram with friend, and we establish there is a pool of 20 champs that came often (may 2 of my mates got them all too, and 2 last all most) and this pool stay the same approximatly 3 or 4 day the same and change a little. Even if there is no "true" random 1/6 of all champions came about 60% of the time ... (60% because 2 got some champions who were not in the actual pool)
