We’ve featured some strange Japanese mobile games here on SD Japan in the past, but this one ranks way up there among the strangest. Alpaka Evolution  is a simple game with simple graphics, but its quirkiness appears to have helped it past a million downloads since the game’s initial release for Android on February 5, and for iOS on February 23.
The game starts out peaceful enough, with a herd of alpacas grazing in a meadow. But you control one of these alpaca, and with a tap or a swipe you can deal a knockout blow to one of your many brothers. Now, before we hear from the animal cruelty folks, I should clarify that the objective of the game is actually to not kill alpacas. But rather the goal is to absorb as many of your fallen brothers as you can, and evolve into a bigger, more powerful alpaca.
The game was developed by a company called Cocosola, and many of its titles appear to be equally off the wall . The app has been the top casual game on Japan’s Google Play store this week, and it has been a top 25 title for iOS for the majority of time since its release on that platform.
I find it pretty fascinating that a game like this can be so popular . There really isn’t anything to drive you to continue than the curiosity of seeing what grotesque shape your alpaca will mutate into. Currently the game is monetized with in-app advertising, but this might be yet another instance where brand merchandising represents a big opportunity. Who wouldn’t buy a plush mutated alpaca?
