ive been trying to delete some of the single player games ive set up for practice. some of the settings have been wrong thats why ive had to quit the game but i cant seem to find a delete button for the game so now im currently still playing all the games ive quit. in my game lobby theres like a million active games. not that it matters but would be nice to clean up a bit if anyone has any ideas

single player games aren't saved once you close the window afaik

Single-player games are automatically deleted as soon as you close your browser window or navigate to a different website. This makes them ideal for practicing with game settings and such.

Multi-player games are never deleted after they start.

don't forget that you can delete Multiplayer games if they haven't actually started turn 0/distribution yet -Aka, before everyone clicks Join-
