Diamond Trophy (Duck Life 9: The Flock)
The diamond trophy is the highest trophy tier for each Arcade training challenge.
Earning it
Meet or exceed the diamond score target for a part of a Beginner or Pro training game in the 
Arcade. Each of the 60 challenges has its own score requirements. See the Arcade article for every target.
Trophy progression
The four tiers are Bronze, Silver, Gold and Diamond. Your best score determines the highest tier reached for each challenge. Improving a score can raise that challenge’s trophy tier.
