Sorry to say but it is the worst app.....It is good till in the Great Hall when it is the time to convince Ben and meal with a friend.....I always give the right answer but it shows out of turn.....I have lost more than 500 coins for this.....it also too long for the energy to get charged.......I can't also duel in the duelling room more than 3 times.....if I do so it tells me to spend gems and play.......please try to change this things
