About This Game

marblebuilds is a creative 2D sandbox where you build marble races, contraptions, and logic-driven machines using a wide variety of interactive blocks.

Design freely on an unlimited canvas, hit play, and watch marbles roll, bounce, explode, teleport, and react to the systems you’ve built.

Build Anything You Can Imagine

Use 100+ blocks to shape tracks, control motion, and create dynamic systems. From simple downhill races to elaborate machines, marblebuilds is about experimenting, iterating, and seeing your ideas come alive.

• Unlimited-size canvas

• Grid-based building

• Name and customize marbles

• Save your creations locally

• Share builds with the community

Dynamic Physics & Interactions

Bring your builds to life with blocks that transform how marbles move and interact:

• Boosters, springs, bumpers, and spinners

• Gravity and antigravity blocks

• Portals (momentum-retaining)

• Breakable paths and explosive marbles

• Shrink and enlarge marbles mid-run

These dynamic blocks add excitement to your builds and make for fun simulation experiences.

Logic & Circuit Systems

For players who want deeper control, marblebuilds includes a digital logic system that lets marbles interact with powered blocks.

• Power wires and logic gates

• Timers, delays, and "Memcells" (T-flip-flops)

• Marble-triggered inputs, such as buttons and observers

• Lamps, marble spawners, and many more outputs

Use circuits to open trapdoors, spawn marbles, control launchers, play music, or push entire sections of your build.

You can keep things simple - or build machines as complex as a computer!

Style, Color, and Decoration

Make your creations unique with decorative and nature-themed blocks.

• Color-customizable blocks (16 colors)

• Signs with custom text

• Nature blocks like grass, logs, leaves, and rocks

• Marble color changers

These physics-less blocks let you add simple beauty to your builds and create visually appealing environments.

Create, Experiment, Share

marblebuilds is about experimentation. Build freely, run simulations, tweak designs, and discover unexpected interactions. Share your creations with the community and try builds made by other players.
