|Information about Battle Frontier|
The Sinnoh Battle Frontier is exclusive to Pokémon Platinum and Pokémon HeartGold and SoulSilver. After defeating the Elite Four and tag teaming with your Rival to defeat Volkner and Flint in Pokémon Platinum, you gain access to the Sinnoh Battle Frontier. In HeartGold and SoulSilver, you gain access to it by just beating the Elite Four. The symbol for this Battle Frontier is a pentagon with a large dot in the edges. These indicate the Battle Facilities: the Battle Tower, the Battle Arcade, the Battle Castle, the Battle Hall, and the Battle Factory. Like in Pokemon Emerald's Battle Frontier, each facility is led by a Frontier Brain.

- Main article: Battle Tower
The Battle Tower is one of the Battle Frontier facilities in Sinnoh. It is a standard 3-on-3 battle. The more wins you get, the harder the opponents get.
- Main article: Battle Factory
You receive random Pokémon. You must fight your opponent with these Pokémon. You get hints about your opponent's Pokémon. As you progress, you receive more faint clues of the opponent.
- Main article: Battle Arcade
The Battle Arcade is a new challenge. It is a standard 3-on-3 battle, but there is a catch. Prior to battling an opponent, the player must spin and stop a gameboard via the touch screen. The space that the player lands on determines the effects of the battle. The effects can affect the player, the opponent, or both; depending on which space they landed. The more wins you get, the harder your opponents get and the faster the board goes.
- Main article: Battle Castle
The Battle Castle is a facility featured in the new Battle Frontier, and is situated in the south-western corner. In the Battle Castle, the player must fight 7 trainers in a row, with the prerequisite being that all hold items must be removed prior to entry. Trainers are also limited to using only 3 Pokémon, all of which have had their levels reduced to level 50.
- Main article: Battle Hall
You choose the type of your opponents. Using Sableye or Spiritomb is effective, because they don't suffer from type weaknesses. Every time you beat a type, their rank goes up. This makes them smarter have a higher level, and higher stats.
- The Sinnoh Battle Frontier is smaller than the Hoenn Battle Frontier.
- The Sinnoh Battle Frontier reappears in Pokemon HeartGold and SoulSilver Versions as the Johto Battle Frontier.
