Rosco Universal GAME
You are given a letter which, in most cases, is the first of the word you need to find and, in others, is contained within the word.
There are several game modes and each has many levels and progressive difficulty. At the beginning , you will find easy words that are commonly used in every day talk; however, in the more advanced levels, you will get rarer and more specific words, until you get to the higher levels where you will find extremely rare words, some of which have not been in use for centuries.
The game is entirely in Spanish (Castilian) and has no English menu.
