An "Auto Battler" is a type of strategy game where players assemble a team of characters or units to automatically fight against opponents. Players typically select and position their units on a grid, and the battles occur without direct control, allowing for strategic planning and resource management. These games often feature elements like team composition, synergy, and upgrades, where players can enhance their units or unlock new ones as they progress. Popular examples of auto battlers include Teamfight Tactics and Dota Underlords, which have gained significant popularity in the gaming community.
