Can I play a multiplayer game against myself?

[TomFCG]

As a developer when testing a game I can play against myself with multiple dev accounts, but I would like to be able to play other games this way. A few games have solo versions but these are usually very different from the actual game. I could of course do this by creating multiple accounts, using a different browser for each and playing in friendly mode, but this would probably still get at least one account banned/restricted. Is there any other way to do this?

Hot seat mode. Click "Available" next to the empty players, and the choice appears.
