You get 1 scene in the free version but you get 7 puzzles that can be anywhere from 2 to 16 peices. When your child finishes the puzzle a voice over tells them what they just put together. I think the full version of this app would be well worth it.
With the Lite version you only get the farm scene, but you about 11 puzzles in that scene. You can also change the difficulty in the settings between easy and hard. When you finish the puzzle it will pop up the word in colorful letters and say it.
I really like Puzzingo's puzzles because there is more interaction than just puzzles. When your child drops the puzzle piece there is a voice over tells them what the piece was. There are also fun little games to play with each puzzle as well.
Kids Super Puzzle is a more typical puzzle game. You get 6 puzzles and 2 modes, 6 pieces or 9. Your child has a faded picture to help them place the pieces. This would be a great game when your child is ready to advance from peg puzzle games.
Awesome Shape Puzzles has three different difficulty settings: single, multiple easy, and multiple hard. You get 2 boards to chose from Toys or Instruments. When you are on multiple mode each item in the pictures become there own puzzles.
Kids Love Puzzles is very simple but great for children learning to use a touch screen and learning coordination. There are 10 very cute puzzles to chose from. When your child is done with the first puzzle they can press an arrow and go to the next.
