SplineDesign and publish playable 3D games for the web
Build browser-ready 3D games without a game engine's learning curve. Combine game controls, physics, collisions, and visual logic to design playable experiences, then publish them to the web where anyone can jump in instantly.
Playable experiences drive deeper engagement than any static content.
How 3D games go from concept to playable release
Spline simplifies the entire pipeline for making 3D games from the first graybox level to polished, playable builds on the web.
- 01
Ideate
Block out levels and mechanics fast with parametric shapes, community assets, and physics. Test movement immediately with built-in first- and third-person game controls, and iterate on the core loop before investing in art.
- 02
Design
Build out the experience: model and texture your world, animate characters, and wire up gameplay with events like collisions, trigger areas, and key presses. Use variables for score and health, conditional logic for rules, and sound actions for feedback.
- 03
Ship to Production
Publish your game as a web experience or embed it anywhere - no installs, no app stores. Players get instant, cross-device access, and you can update the live game as often as you like.
Remix Playable Games from the Community
Discover game templates and mechanics to jumpstart your playable 3D projects.
Questions, answered
Can I make 3D games for free?
Yes! Spline offers a free plan that lets you design levels, add physics and game controls, and publish playable games directly to the web. Perfect for game jams, prototypes, portfolio pieces, and marketing games.
How can I start designing a 3D game?
Getting started is quick. Add game controls to a character, enable physics on your level, and you have a walkable world in minutes. Remix game templates from the Spline Community to study mechanics, or build your own from scratch.
What is Spline and how does it work for game design?
Spline is a real-time 3D design tool with game-ready features: first- and third-person game controls, a physics engine, collision and trigger events, keyboard input, variables, and conditional logic. You design both the art and the gameplay visually in one editor.
What game mechanics can I build without code?
Movement and camera controls, jumping, collecting items, score and health systems, doors and switches, checkpoints, win and lose states, and physics puzzles. Events and actions connect everything visually, and variables carry your game state.
How do players access games made in Spline?
Instantly, in the browser. Publish your game to the web or embed it in your site, and it runs on desktop and mobile without downloads. That makes Spline ideal for playable ads, promotional games, and rapid game prototyping.
Do I need game development experience to make games in Spline?
No. Spline removes the traditional engine learning curve: no scripting, building, or deployment pipelines. Designers can create complete playable experiences visually, while developers can extend games further with code exports and APIs.
