Where To Sell A Game?

Anywhere I can sell a game ready to be published?
I have this Escape Zombies game ready to be published I want to try to sell.
This game is NOT published yet.
Thanks,

Here are some well-known sites:

Edit: You didn’t mentioned here that your game is mobile only… In that case, you have to become a registered developer for iOS (via Apple Developer Program; fee is $99/year) and set-up a Google Play Developer Account (fee is $25 (one-time), more help here).

Thanks, but I want to sell the entre game to a new owner. So the new owner can publish it.

You could give Unity Connect a try, though I’m not sure if that’s the best place for such offerings. A quick Google search (“sell game source code”) brought up various sites, so maybe give them a try too.
