LetterShaker app for iPhone and iPad

With Letter Shaker some letters of a word have been lost. You have to put them back into the right position.
You can do this by touching the right letter and moving it with your finger in the right position. If the word is complete again you can hear the sound of the object the word describes - a dog barks, the bus blows his horn and from the castle you hear a spooky sound. If you like the sound you can hear it again by touching the picture - but it only works if the word was written correctly.
If the wrong letter is selected it tumbles back into its original position. Actually you can even try to kick the letters into the right position - when they hit the "wall" they bounce back behaving like real physical objects thus providing additional fun for kids.
If you are still in learning mode and if you didnt find the right letter after three trials an outline of the correct letter is shown and then you can drag and drop the right letter in the right position.
If you become a real expert you can move to the next level. While on level 1 only one letter is missing and help is provided you have to enter 2 or 3 letters on level 2. On level 3 you even can just see the first letter. You have to fill in everything else - no problem if you are an expert in reading and writing.
OK, you may think I can read and write since a long time you may as well use LetterShaker to learn some basic words in another language as Letter Shaker is available in English, German, Spanish, French or Italian.
By the way if you are a lefty you can just flip your device and the layout adjusts.
