All Random Summoner's Rift (ARSR) is ARAM on the Summoner's Rift map.
- Champions are randomized from your own champ pool and the free-to-play rotation.
- Gameplay is the same from a normal Summoner's Rift game.
- All other gameplay mechanics are the same: you still get ambient gold and exp, reroll, etc.
- Mastery rewards also work the same as on regular SR: you can still earn Hextech Keys, Hextech Chests, and Mastery Tokens.
- Rerolls using the same as ARAM.
