Technically yes but there’s a trick to it. If you finish your custom game or Scrim properly and the match is saved to Riot’s servers, you can easily import and analyze your game. If you leave the game before Riot saves the match data, we recommend that you do the following: 

  1. Record your match video with RiftGG

  2. Perform your analysis manually through the button tab. You can assign all the ‘default’ actions like Champion Kills, Baron, Dragon, etc., but you will also be able to tag other actions like Ganks, Teamfight, etc.
