Hi,
Thank you for posting your question in Microsoft Community!
So you want to play Chess Titans on Windows 8.
If you take a look in the Windows Store app, there are several Chess games available there.
You can go to your Start screen by either clicking in the bottom left hand corner or pressing the Windows key, and then go to the Windows Store app.
Once in the Store, you can then search for apps by pressing Windows key + C and click Search in the Charms bar, and search for Chess games from there.
Note: The games from Windows 7 are not available by default in Windows 8. Keep checking the Windows Store for available games.
You may want to click here "Apps in the Windows Store" it tells us about variety of great apps available for Windows 8
Hope it helps!
