Kids Slide Puzzle World is a brain-teasing game developed for children. The board looks a lot like old-school 8-puzzle plastic sliding games where your objective is to move tiles until you reveal an image.
The app doesn't bring you extraordinary artworks. However, the images from the challenges are amazing. Also, you have access to options to resize the main window's resolution and disable sound effects if necessary. What's more, the app automatically saves your progress (when closing the main window by accident while playing a challenge).
You can choose between 3 difficulty levels, each with an individual set of missions. You don't need to complete a mission in order to unlock the next one; the app lets you choose which challenge to play.
The only thing that bothers me about this application is the fact that it doesn't provide you with all challenges for free. You need to make an in-app purchase in order to have access to all missions.
Other than that, not much more can be said about this puzzle game. The app is available in various languages, automatically saves your progress, and has simple rules. In my opinion, you should give this game a try and see if it's worth buying its full version or not.
