#23 Match up Checker

Learn how to get the Match up Checker in Pokémon Diamond and Pearl by catching 5 Safari Pokémon. Understand its breeding compatibility function.

Location: In the Great Marsh, an NPC (non-player character — anyone the game controls, not you) will give you the Match up Checker when you capture 5 Safari Pokémon in a single game.

Function: This item allows you to select two Pokémon and displays how well they will match up for breeding. The number of hearts shown in the upper part of the screen indicates the compatibility level.
