A great puzzling app.
Slider Puzzles: The Invaders is an excellent app for training your child's memory skills and its logical reasoning. The app is about puzzling a picture. There are five different pictures given which are cut into a different amount of pieces - 2x3, 3x3, 4x4 - changing the level of difficulty. The app can be used for different ages. The different pieces need to be slidderd to find their right spot. Your child needs to memorize the picture because it isn't shown as a hint while puzzling. Touching the button 'more games' will open the publisher's website.
