Welcome to Android Central! I don't understand the issue--what do you mean when you say you accidentally unlocked the options to download the games? It sounds like you're saying you're unable to download your games--have you logged your tablet into your Google account, gone to Google Play, swiped in from the left and tapped My Apps, then All? All of the apps you've ever installed should be in that list, and you can select which ones you want to reinstall.
Or are you talking about wanting to restore data that was backed up to your Google account?
