As recorded at collection: 7000 free points upon signing up for Marble

World Labs’ Marble is a service that creates 3D world scenes based on user input. According to a review, signing up gives you a free version and 7000 points, letting you create up to 4 world scenes.

After signing up for Marble and signing in with a Google account, you can use the free version right away. After using points to create a scene, you can explore the space like a 3D game using the left mouse button and the W, A, S, D keys, and freely change your viewpoint.

The paid version lets you create up to 12 world scenes for 20 dollars. Created scenes are displayed as entire spaces, like virtual reality games, and can be experienced in virtual reality mode if you have a virtual reality device. However, some areas may be blurry or less polished because they are not fully generated.
