Pokémon Platinum Version Tips

Battle Roulette
When inside the Battle Arcade, you have to choose 3 Pokémon and you'll be put into the contest. At the beginning of the battle you have a board with different squares representing different things which could happen. This can effect you or your opponent. Once you complete 7 battles, you are rewarded with 2 Battle points. Once you do 20 battles, your 21st Battle will be with Roulette Goddess Daria. If you defeat her, you get the Silver Print. Do another 28 battles, and face her for the Gold Print.
