This game is in Brazilian Portuguese language.
"Chuva de Letras Brasil" is a game for children. You should get the letters to make words.
In the middle of the screen you have a clue about which word is drawn.
Each correct letter adds a point. Each wrong letter subtracts a point.
If you need more a little help, get the bright letters. They do not give points, but are always letters of the drawn word.
Good game!
