The Pokémon Center is an area where you can trade with other trainers, purchase items, and get Daily Gifts. It can be accessed via Sam's blog. The "Trading" button on both PTD 1 and 2 game menus, and the "Inventory" button on the PTD 1 game menu can take you to the Pokémon Center.
There is also a warning to log out of PTD 1 or 2 as it might corrupt data. If you open the Pokémon Center while playing PTD 1 or 2, the game will be unable to save.
Pokémon Center Features
In the Avatar Store, you can buy different avatars using your SnD Coins.
Once a day, you can participate and try to win rare prizes. I recommend using more than 1 account for this feature so that you have higher chances to win SnD Coins every day.
Check your items and change your avatar for your profile here.
Play the slots to win Casino Coins which can also be won from the Daily Gift, you can use them to buy rare Pokémon with a 1% chance for them to be Shiny, you can also get them Shiny automatically if you pay more Casino Coins for it. This feature cannot be used before completing the level Lavender Town. In PTD 2, the Game Corner is in Goldenrod City, and therefore cannot be used before reaching that level.
Go here to select one of your Pokémon and put it up for trade. Therefore, Other players will be able to request trades for your Pokémon. Once you put your Pokémon to trade, you will not be able to use it in your game unless you call it back.
Your Trade Requests
Go here to see if anybody has requested a trade with you or if any of your requests have been accepted. You can also call back your Pokémon if you don't wish to trade it anymore.
Go here to search for trades that other players have posted, you can also request a trade for their Pokémon.
Remove Hacked Tag
Go here to remove the Hacked Tag from your Pokémon. The tag may be removed using 1 SnD Coin or 500,000 Casino Coins. 10 SnD Coins will allow you to remove the tag from all your hacked Pokémon at once. In PTD 2, it is 1 SnD Coin or 50 Daily Coins to remove it from 1 Pokémon or 10 SnD Coins to remove it from all of your hacked Pokémon. But the 10 SnD Coins choice is if you have 10 or more Hacked Pokémon in your PTD 2 profile.
