About

Bison Attack!

Read full description

One of you is the bison. Everyone else just wants a photo. Bison Attack is a fast online party game for 2-8 players, set in a pixel-art Yellowstone. Tourists sneak through the park to photograph the wild bison - the closer the shot, the bigger the score, and a selfie right next to it scores most of all. But every round, one player is the bison, and the bison's job is simple: flatten everybody. HOW A ROUND WORKS • Create a room and share the 5-letter code (or invite link) with friends • Each round, one random player becomes the bison • Tourists race to the target score before time runs out • Get trampled and you lose points - and your dignity SURVIVE THE PARK • Hide in bushes - but don't camp, snakes live there • Slip through tree gaps too tight for the bison • Stay out of the hot springs. They boil tourists • Enrage the bison with too many photos… then run MORE • Four tourist types with their own quirks: kid, teen, adult, elder • Playing alone? Add an AI bison and robot teammates • Cross-play: friends without the app join instantly at bisonattack.com • Every room gets its own randomly generated park • Free to play, no account needed
