This viral vibe-coded game turns Google Maps into a time machine

You are on a street. You see stone buildings, gas lamps, some men in long coats. Is this somewhere in Europe? Probably. But, when? That is the question that Wen Ware adds to the formula of Geo Guessr, a popular game that shows Google Maps locations all over the Earth and asks players to guess where it is. The free browser-based Wen Ware drops you inside an AI-generated historical panorama, completely navigable in virtual reality, and gives you 60 seconds to do two things: pinpoint the location on a world map and adjust a timeline slider to the correct year. The person behind the project goes by @underpaid_mom on X. With no real name, no company, the game was created as a submission for vibejam 2026, an AI-based browser game development competition, and appeared on the internet in late April 2026 with the description “a time-traveling GeoGuessr-inspired game where you can explore immersive 360-degree historical scenes.” [Screenshot: WenWare] The game became an instant viral hit. Each game session offers five chances to pinpoint the spacetime coordinates of five different scenes, moments like the Wright brothers’ first flight, the coronation of Charlemagne, or the creation of Leonardo da Vinci’s The Last Supper. You look around and analyze the scene like a detective: the silhouette of a vehicle, the cut of a uniform, the shape of a roof, a flag that rings a bell but you can’t really place. Then you submit your two answers. First, the year, using a slider. Then, the place on a Google Maps map, overlaid in the lower right corner of the screen. The game scores them simultaneously, showing you how close you are to both on a map, with a card on the right top corner that explains to you what you just saw. Each time, the scores will be added to a total, which may get you into the Top 100 global leaderboard in each category: modern, medieval, ancient, or, the hardest of all, any of the three ages.
