What it is
Encierro is a multiplayer survival game that @milanm_ made for Vibe Jam 2026, set at Pamplona's San Fermín running of the bulls each July. The author's pitch: dodge rampaging bulls through festive Spanish streets and outlast everyone else in tight-quartered chaos. The home screen lays out the scoring: every second alive is a point, running close to a bull earns bravery points, jumping a bull is worth 50 and grabbing a sangria cup 20, though the sangria makes you wobble; you can also hide in passages the bulls can't follow. Share a room code to run with friends, or go solo and bots fill the crowd. The jam rules require at least 90% of the code to be written by AI; the jam page doesn't list which AI tools were used.
Who it's for: players who like chaotic multiplayer and are curious about festivals like San Fermín.
Before you start: under Vibe Jam's rules it's free to play in the browser with no sign-up; you enter a runner name. Playing with friends goes online. The game includes picking up sangria, which makes your runner wobble. The pages are in English, and they don't say whether it works on phones. No age rating is given.
