What is the name of walkthrough videos, for free play mode for video games

Walkthrough videos for free play mode in video games are often referred to as "Let's Play" videos. In these videos, players typically showcase gameplay, share tips, and provide commentary while they explore the game in a more casual or free-form manner, rather than following a strict guide or walkthrough. Other terms that may be used include "gameplay walkthrough," "playthrough," or simply "gameplay video."
