3JS TTD is a free strategy browser game by HappyMonkeyAI. Play it on desktop, with no download.
ThreeJS TTD is a browser-native 3D logistics management simulation game built from the ground up using Three.js. Currently in Early Access, the game offers a complete sandbox tycoon experience where you design, construct, and optimize regional supply networks. Generate custom procedural worlds by tweaking map sizes, terrain seeds, industry clusters, and town density. Lay down complex road networks, bridges, tunnels, vehicle depots, and loading stations to keep cargo and passengers moving seamlessly between destinations. Reliably delivering goods directly stimulates dynamic city growth—expanding small settlements into bustling urban centers with high-rise towers—while enabling connected factories, farms, and refineries to level up their production output. Featuring smooth 3D camera controls (pan, zoom, and rotate), full fleet management menus, and an integrated audio player, ThreeJS TTD delivers a deep, accessible transport management sandbox right in your web browser.
