Tiny Auto Knights is a strategy game about assembling a custom deck of heroes and arranging a team for battle. Each hero brings distinct skills, and battlefield placement matters: positions determine the order in which attacks and abilities are used. Once combat begins, the team fights automatically, so preparation and formation shape the encounter rather than moment-to-moment commands.
The planning has several layers. Merging identical heroes raises their level and unlocks stronger skills, while effects such as armor, poison, and freezing add tactical complications. Victories award Unlock Tokens for acquiring heroes, and players can build synergies from their chosen roster. Relics provide passive bonuses, with rewards offered as heroes level up, giving each run opportunities to strengthen a team in different ways.
Players can choose ranked or casual games, face teams belonging to other players, or take on weekly challenges built around a curated deck. Custom decks can also be shared with friends and the community.
