Pokies are a series of invincible mobile stone blocks that deal damage on contact. Revelations added the following variants.
Button Mashers behave like Wall Huggers, circling walls and objects and only deactivating if all buttons in a room have been pressed. Unlike Wall Huggers and their respective variants, Button Mashers can trigger Traps when they slide over them.
Despite what their name may imply, Button Mashers can not press buttons and will merely pass over them undisturbed.
