Two mobile games in one
Mobile puzzle games usually don't get a lot of gamer cred. It's a shame, because a lot of them really break the mold, and provide pretty deep experiences if you let them. One such game is Disney's Where's My Water?, and its very similar clone, Where's My Perry?
Both of them are basically just elaborate versions of Pipe Mania (I totally remember that game at launch, and now feel super old), but they're a ton of fun in their own right.
Today, you can grab the free app Where's My Holiday?, which is basically a mash-up of the two games into one small 12 level package. It's on iOS right now, and it will be coming to Google Play at some point today. Even if you're not a Disney or Phineas and Ferb fan, free can't hurt, so check it out if you enjoy quick puzzle games.
