Time Heroes is a free multiplayer idle pet-collecting game created by Timelands, designed to play in a desktop browser on a PC or laptop without a download. Players mine for ore, hatch eggs, collect pets and unlock new worlds, progressing alongside friends in a shared game universe. Each world has its own eggs, pets and challenges, while the Codex tracks discoveries and the many possible pet rarities, forms, sizes and special traits.

Players can join colonies to cooperate and compete, enter weekly leagues based on trophies earned from hatching pets, and travel between worlds aboard ships that grow as they advance. The game also features crafting, pet evolution, combat, a Tower, mining resources and a prestige-style Paradox reset that preserves permanent power and rank. TimeStars accrue through time spent playing and can be used for in-game options such as skipping waits and purchasing gems or Gamepasses. Timelands supports the game with updates and an online handbook featuring guides, reference information and FAQs.
