I can't think of any but wouldn't it be cool to just get your wife pandora's box again - assuming that you use the word 'loved' meaning you no longer have the game, as opposed to her now having a dislike to the game.
Gamehouse http://www.gamehouse.com/ has free hidden objects, match 3 and other games (today is a time management game) avail to download, a different one each day. It's free if you don't mind putting up with adverts interrupting your play - they seem to have become more frequent recently - or you can buy a "funpass" for $19.99 per month to be rid of them altogether for over 900 games (apparently - I haven't bothered buying it). There's some good quality games included.
