I think we've all experienced at one time or another a simple but surprisingly entertaining game that makes hours seem like minutes, hooking you from the first time around. Well, Plants vs. Zombies is one of those games.

From the makers of Bejeweled and other well known casual titles, this tower defense game features probably the most common foe in the history of videos games: zombies. But there's a twist. Instead of you fighting them, your defenses do all the work. The seeds you place in your front yard sprout into plants with all kinds of zombie-fighting properties. You have to be quick, aware and strategic when defending against the ever growing hordes of zombies, but if you choose wisely your home should stay zombie-free.

The only catch is you'll have to go through the Origin client to get the game for Windows or Mac, but if you are a gamer odds are you've already got it. Once you download and install Origin, search for 'Plants vs. Zombies Game of the Year Edition' and you are set. This offer is available until May 28, after that date the selling price will go back to $2.99.

The second iteration of the game, Plants vs. Zombies 2, has been out for a while and is free to play with in-app purchases, but you can't beat 100% free.
