League of Legends Steam Deck Guide: How to Play LoL Portably

League of Legends is one of the most played games in the world because of its technical accessibility – even the most basic PCs and laptops can run League of Legends at a functional level, and because of that, LoL is also playable on Steam Deck. Steam Deck, a handheld gaming device that can also be docked and played like a console (similar to the Nintendo Switch), was released by Valve in February 2022 and is a convenient way for players to access their Steam library from anywhere.

However, YouTuber TheWereCat has shown that with a short script and a meticulous series of steps, League of Legends is playable on Steam Deck. Here’s a guide on how to install League of Legends on Steam Deck.
