Weird Park: Scary Tales - A Hidden Object Adventure asks you to solve a mystery in a spooky old town involving missing children. Ghostly images of these children appear occasionally, directing you onward to find out what has happened to them. Along the way, you have to acquire objects and tools that you'll need to keep going by solving mini-puzzles or finding them in the scenery.
Like most hidden object adventure games, Weird Park: Scary Tales shows a brief introductory video when you first open it, which you can skip if you choose. This sets the stage for your quest, which involves gathering objects and interacting in the scenes. The hints are helpful enough without making the game too easy, so even if you use them as much as you can, you'll still have some work to do on your own to puzzle things out.
This app is free to download and play, but if you want to completely unlock all of the features, you'll have to spend $1.99 on in-app purchases. Like any hidden object game for the iPhone, the small size of the screen can make it hard to spot the small hidden objects even though the graphics are great. But if you're looking for a fun game to take with you, this is certainly worth a try.
