Unicorn Evolution Simulator is a free game app developed by Tapps Tecnologia da Informacao LTDA. It is an addition to the Evolution series games, featuring the most majestic creature - unicorns. The game is a combination of alpaca-like evolution, 2048 and incremental clicker games, with doodle-like illustrations.

The game is easy to play, where players need to combine unicorns to evolve them into their most curious, exotic, and bizarre forms. One can drag and drop similar unicorns to create new creatures or tap fiercely on a unicorn to make eggs pop. The game also features a new place for supreme beings called Pantheon, where they can look down on us mortals and laugh at our misery. However, players need to watch out for impostors trying to steal the unicorns' spotlight.

Unicorn Evolution Simulator has different stages and many unicorn species to discover, with various possible endings to find your destiny. Although the game is free to play, some additional content can be purchased for real money in-game.
