Secret Word Gardens

Like most of the new games in 'Pogo' there are no proper instructions, ugh. for a challenge to have "get secret words" but doesnt tell you if they're marked as such or where to get them etc is no help at all! I've managed to play the first 3 challenges, though felt I was doing it 'blind' cos of no proper direction!! Would think EA would give us more than they do, lol
