Pedro Martínez: I've a game at home which is on a CD. I can choose the level " easy " for children or else the " hard " level for adults. At the beginning, I was asking myself what could be the difference. I've noticed that the letters which are given are different : example : in the " easy " game, you receive more vowels and letters than we can find in many words, but in the " hard " game, you more often receive difficult letters as " K ", " W ", etc...
Of course, it's always more easy for the player which knows better the language, but it's also interesting for the beginner.
