Breakable rocks are a type of obstacle appearing in many core series games, commonly found on rugged routes and in caves. To get past them, the player must use the help of a Pokémon to break them. They appear in Generations II, III, IV, and VI, and Pokémon Brilliant Diamond and Shining Pearl, in which they can be broken using the field move Rock Smash, and in Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, in which they can be broken using the Ride Pokémon Tauros Charge and Sharpedo Jet.

In regions other than Sinnoh, it is possible for the player to find something after breaking a breakable rock. In Generations II and III, there is a chance of a wild Pokémon appearing. In Pokémon HeartGold and SoulSilver and in Generation VI, there is a chance of either a wild Pokémon or an item appearing. In Pokémon Sun, Moon, Ultra Sun, and Ultra Moon, there is a chance of an item appearing.

In Pokémon X and Y only, the player can also come across cracked walls in and around ruined buildings. These, like breakable rocks, block off certain areas and can be broken using Rock Smash. However, they do not leave behind any items or Pokémon upon being destroyed.

Generation II

In Pokémon Gold, Silver, and Crystal, when using Rock Smash on a breakable rock, there is a 60% chance that nothing will happen afterwards and a 40% chance that a Pokémon will appear.

Ruby, Sapphire, and Emerald

In Pokémon Ruby, Sapphire, and Emerald, breakable rocks on Route 111 block the player's advancement north until they have received the Dynamo Badge. Depending on the location, players have either a 1/9 or 5/36 chance of encountering a Pokémon each time they smash a rock. This chance can be modified by a bicycle, White Flute, Black Flute, or Cleanse Tag.

HeartGold and SoulSilver

In HeartGold and SoulSilver, the game generates a random number from 0 to 99. If the generated number is lower than the location's first %, the game will generate an encounter with a wild Pokémon from the encounter table. If this fails, or there are no wild encounters in that location, it will generate a random number from 0 to 99 for an item instead using the second %; if that check fails as well, smashing the rock yields nothing.

Generation V

In Generation V, Rock Smash is not a field move, and there are no breakable rocks like in other games. In Black 2 and White 2, however, the player can help clear a section of boulders in Clay Tunnel if a Pokémon in their party knows Rock Smash.

Generation VI

In Generation VI, when using Rock Smash on a breakable rock, there is an even chance that: nothing will happen afterwards, a Pokémon will appear, or an item will appear.
