These games usually include a lot of forbidden things such as music and
mixing between men and women.
To my knowledge, one can’t get qualified to these games without calling a
special number that would charge a lot of money per minute deducted from the
caller’s account. By paying this money, he would be like gambling as he
wouldn’t know after paying all this whether he would be chosen or not and
after that whether he would win or not.
Therefore, it is not permissible to participate in such games.
