Smart Hangman

Smart Hangman !
At the beginning of the game the player gets a number of coins in the wallet. The wallet contains a maximum of 6 coins. Using these coins the player must guess the hidden word.
Possible Actions:
1) Chose a free Letter from the first category.
2) Buy a Letter from the second category.
3) Buy a Hint. The Hint is either a word or a phrase that it is associated (in some way) with the hidden word.
4) Get 2 Coins (+2) after watching an ad.
5) Buy a Life.
6) Give the Word. If you have found the hidden word, you can either speak to the microphone, or type the word.

The game has three difficulties: Easy, Medium, Difficult. These refer to the hidden words. The Easy is suggested for small Children. If you find the hidden word you will get 1, 2, or 3 points for each remaining coin.

By winning points you move from one level to another. In each subsequent level the game becomes a little bit harder (for example you earn a little less coins, or the purchases become more expensive).
