How do you get first place in the Colosseum in DragonVale?

Answer 1

Each day there is an event in the Colosseum. The type of event is visible on the flags flying outside the building and on the event screen. Each event is based on one of the elements in the game.

To choose a dragon to compete, touch the Colosseum and view the event screen. At the top of the screen is the event type. The strategy is to choose what you consider the best dragon in your park to compete in that event type. For example, an Earth Dragon might win an Earth based event. A higher level dragon gives a better chance of winning. However, the results may be completely random, for example a Fire Dragon may win a gold trophy in a Cold event.

Every 24 hours the event type changes. After you place your dragon in the Colosseum you cannot remove it for 24 hours or speed up the event using gems. The dragon in the Colosseum does not earn income in its habitat during the event and you cannot fill the vacant habitat spot with another dragon nor sell its habitat.
