Since the Minnesota Zoo's free educational video game, WolfQuest, launched late last year, it has attracted attention and gamers from across the globe.
More than 100,000 people have downloaded WolfQuest and it averages more than 1,000 new users every day, according to figures provided by the zoo.
Michelle Housenga, the WolfQuest project coordinator at the zoo, said downloads come in waves as new countries learn about the game. She said its popularity stems from extensive news coverage, including from National Public Radio's All Things Considered and Iran's Tehran Times newspaper.
"I think the response we're getting is exceeding our imagination," she said.
The online video game is a lifelike simulation of a wolf hunting, communicating with other wolves and mating (only nuzzling is shown before the screen goes black and the wolf pups appear). The goal of the game is to survive, find a mate and start your own pack.
Collin Shinkle, 14, has been playing WolfQuest from Lincoln, New Zealand, since he learned about it through the news. He said he plays video games frequently and has a large collection of them, but WolfQuest is by far his favorite.
"I've never played anything quite like this before," he said.
He said he revels in hunting and communicating through gestures as a wolf, one of his favorite animals. After playing WolfQuest and visiting its online forums, Shinkle said he's learned how wolves hunt and communicate.
