On Facebook, you can un-authorize a game you have played, but still many many days later when you open the game – you can authorize it again and continue playing from the exact point you left off.
My question is whether there is any way to delete your game progress without completely deleting your Facebook account?
Sounds like you (or someone else) blocked the game on your account.
Go to your privacy settings to see if it is blocked.
From the Facebook News Feed click on Apps and Games in the left sidebar, or go to https://www.facebook.com/games. Any requests from friends should appear at the top. Go the upper right corner of the request and click the X that appears. That will hide that request and provide the option of blocking the application, or ignoring all requests from that person.
If you are not receiving requests/invites but it is just appearing your News Feed, and you do not want to see those, you can hide all game stories from particular people, or all stories from a particular game. Just hover over one of those posts in your News Feed, click on the ∨ that appears in the upper right corner of the post, and choose the desired option.

The Games are just hosted on Google+ / Facebook, and the game progress is saved in the servers of the Game Developers (Eg.: Zynga, Digital Chocolate, Wooga). You cannot delete your Game progress as such.
Even if you revoke the access of the Game from Google+/Facebook, the progress will not be deleted and you will be able to continue playing the game from the same point by opening the game again and granting the game access to your account information once again.
Deactivating Facebook account also does not helps. In Google+, even if you delete your complete Google+ Profile, your progress does not goes away. You can always recreate the Google+ account with the same GMail address and continue playing from the same point.
Deleting the whole Facebook account (after waiting for the 15 Days "Deactivation" Period) and deleting your whole Google Account (with GMail Address, Contacts, Docs, Calenders everything gone), can alone prevent you from continuing your game again.
Even then, your game progress will be available in the servers of the company, it will just become in-assessible to you for the rest of your life.
