PokéBox is a browser-based simulator that revolves around the biomes, ecosystems, relationships, and lifecycles of Pokémon. The basic goal of the simulator is to encounter all the different species and forms of Pokémon using a only single box and a handful of starter Pokémon as seeds. Your starter Pokémon can be used to attract other similar species, and then those can be used to attract even more. Check your Pokédex after playing for a bit to see how many species you've registered so far!
Filters - Use the Normal Mode filters below if you only want to encounter Pokémon up to a certain generation:
Add up to 10 different Pokémon to your box and then press play. Watch as they grow, evolve, multiply, and eventually die leaving their offspring to continue the cycle. The kinds of Pokémon you add to a box can alter its appeal to other species and can greatly affect its resident's growth and breeding behaviours over time. Whenever you're ready, STOP the simulator then try a different combination of starter Pokémon.

Each species that lives in your box contributes to the global Type Appeal values in some way. Fire types, for example, attract other Fire types... but they also repel Bug, Grass, and Steel types due to their type-advantage over them. Likewise because Fire types are weak to Water attacks themselves, they may inadvertently attract Water type Pokémon to the box as well. All basic Pokémon influence a box's appeal values but fully-evolved and special or legendary Pokémon influence it a bit more.
Type Appeal values affect many things, but the most notable are evolutions and breeding. Some Pokémon may find a certain type more or less appealing, and may either evolve into or produce offspring with a new typing to compensate. If the appeal values are just-right, Pikachu can evolve into Psychic types, Ninetales can give birth to Ice types, and Gloom can decide to shed their Poison type to become pure Grass.
Most Pokémon grow and eventually evolve on their own, but some require very specific conditions to reach their next stage of development.
