Plants vs Zombies: Free for a limited time!
Another staple for any iDevice, Plant vs Zombies is free for the iPad and iPhone/iPod Touch. This game is not universal so if you have both devices, make sure to download each of them. I’m glad my time progress is not tracked in game because I can’t even imagine how many days I’ve sunk into it. I wasn’t able to find how long the game will be free so download it while you still can.
