Backdooring is a high risk strategy where a champion enters the enemy base to attack structures such as inhibitors or the Nexus without an allied minion wave. This usually occurs when the opposing team is distracted by a major objective or a teamfight elsewhere on the map. Champions with strong mobility, fast structure damage, or stealth excel at backdooring because they can slip through fog of war and strike quickly.
Successful backdoors require careful timing, strong Map awareness, and an understanding of when the enemy team is too far away to respond. Players often pair backdoors with wave pressure or a coordinated Split push to force opponents into difficult decisions. Although backdooring becomes more viable once base turrets are destroyed, it remains inherently risky because getting caught alone can cost major objectives.
When executed properly, a backdoor can immediately end the game or create a decisive advantage, making it one of the most dramatic strategies in League of Legends.
