Ídolos

Ídolos is a singing game based on the American Idol/Pop Idol TV show. Players assume the role of "wanna-be pop stars", and must sing their way up, with each duel eliminating one candidate. Every round a new music style is randomly selected; after each duel, votes are casted and the one who receives less points is eliminated.

But there is another catch: every player has a secret candidate, and the main goal of the game is to make him/her win the contest. And since each grade can only be used once, there is some strategy involved in the voting process.
