Idle games, also known as incremental games, are video games built around continuous progression through automated actions and resource generation. Players earn currency, materials, or other rewards over time and invest them into upgrades that increase production efficiency. The genre focuses on long-term growth, optimization, and unlocking new systems while progress continues with minimal direct input.
Idle games are designed around gradual expansion and resource accumulation. Players often begin with a simple task such as earning coins, gathering materials, operating a small business, or managing a production line. As profits increase, new upgrades become available, allowing progress to accelerate and larger goals to be reached. Many idle games include prestige systems, research trees, automated workers, and unlockable features that keep progression moving forward.
The genre covers a wide range of themes, including business management, city development, farming, mining, transportation, monster collection, and economic simulation. Some games focus on operating shopping malls and hotels, while others revolve around expanding airports, building civilizations, or managing production networks that generate increasing amounts of resources.
