While Diamond and Pearl only offer the Battle Tower, in the Fight Area, Platinum adds four additional arenas for making challenges. This expanded area keeps the same moniker as was used in Emerald, The Battle Frontier.
As you progress through the Frontier you will earn BP (Battle Points). Below the things that can be purchased for BP, in each game, are detailed below.
There are two corners where you can spend BP.
The first corner, The Exchange Service Corner, is divided into two stands. In Platinum these stands are located outside in the middle of Frontier Square, in Diamond/Pearl these stands are located inside of the building you pass under while heading toward the Battle Tower.

You will then proceed to try and scratch-off three of nine greyed out areas to reveal Pokémon that match one of the prizes displayed on the top screen.
Ditto can be used to substitute for a Pokémon if you have two others that match, or two Ditto and one Pokémon. A list of the available prizes follows...
