How to Use Rock Smash

Press the A Button Towards the Cracked Rock

To use Rock Smash in the overworld, press the A button towards a brown cracked rock. Activating the hidden move destroys the rock, allowing you to access new areas.

Defeat Roark to Use Rock Smash as a Hidden Move

You cannot use Rock Smash as a Hidden Move unless you have defeated Roark, the gym leader at Oreburgh City. His team consists of Rock-type Pokemon so be sure to use Grass-type or Water-type Pokemon to deal with his Geodude, Onix, and Cranidos.

After defeating him, you can use Rock Smash to destory cracked rocks to access different areas of the Sinnoh region that you can't access before.

Use Poketch and Switch to the Hidden Moves Screen

You can also use Rock Smash as a hidden move from the Poketch app. If the Poketch app does not appear in the upper right corner of the screen, press the R button twice. If a small screen is displayed, press the R button once to enlarge it.

Once the Poketch app is displayed, press the red button to switch to the Hidden Moves screen and select Rock Smash from the menu.

It is recommended to simply press the A button towards the cracked rock as it is faster to do so.
