Been building atlas the past few months. A mobile webapp game, like Geoguessr, but with answer options (correct vs two decoys) which makes it a bit quicker.You re dropped somewhere and have to guess correctly as fast as possible. Every day at midnight UTC 5 new places will appear, same 5 for everyone in the world. So that’s the global league table.Every place you get right fills in your personal atlas map, which slowly becomes a picture of the places you know around the world.There are also live rounds where you can challenge friends (everyone sees the same place at the same moment) and slow async expeditions where a group fills a shared map over weeks.In ‘Tourist’ mode you play global locations around the world (randomised).In ‘Local’ mode you play neighbourhoods of cities or islands. In order to “own” a place you have to Ace it (5/5) - then your atlas map lights up with that place in blue.Some choices we made building this that HN might appreciate: 1. There is no “account”, no signup, no cookies, no ad SDK, no 3rd party analytics. Identity is a random uuid in localStorage and everything works from the first tap. The server sees the gameplay it needs to run the game. Your answers and how fast you locked them - tied to that uuid and nothing else. 2. The whole game is one HTML file, no build step. Answers are sealed server-side so the client never holds the labels. (Protects from cheating!)It s free and it s a game about the world, let me know any comments or questions I’m here to answer!
