About This Game marblebuilds is a creative 2D sandbox where you build marble races, contraptions, and logic-driven machines. Share your creations with the community, and challenge yourself in puzzle and platformer modes. Design freely on an unlimited canvas, hit play, and watch marbles roll, bounce, explode, teleport, and react to the systems you've built. Three Ways to Play Sandbox : Build anything, no limits. Race marbles, track finish times, and experiment freely on an endless canvas. Puzzle : Place a limited set of blocks to guide marbles to every star. Levels range from quick placements to deliberate, engineering-style thinking. Create and share your own puzzle levels, or try ones made by other players. Platformer : Take direct control of your marbles. Collect all stars to finish the level. Switch between marbles at any time. Freeze the action, pick a new marble, and continue. A built-in Campaign teaches you the blocks through increasingly creative levels. Build Anything You Can Imagine Use 150+ 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, customize, and race your marbles Save your creations locally Publish your builds and browse the community Move Everything The full game introduces block movers that bring your entire track to life. Instantly slide blocks, marbles, and circuits as a unit along the grid. Everything moves together. Circuits on moving blocks stay connected. Machines can reconfigure themselves mid-run. 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 Breakable paths and explosive marbles Marble size-changing, marble color-randomizing, and marble speed-filtering Wind Blowers that push marbles with highly interactive forces Create winding and splitting paths using Glass and Regenerating Breakable blocks Logic & Circuit Systems Marblebuilds includes a digital logic system . Marbles interact with wires, logic gates, timers, Memcells, and marble-triggered inputs, and the system outputs back into the physical world. Control your creations with Interactive Buttons and Keybinds. Build anything from a simple door trigger to a working computer. Use circuits to open trapdoors, spawn marbles, control launchers, play music, or push entire sections of your build. New builder blocks let your circuits change the world. Block Rotators, Placers, and Destroyers make the world transformative, especially using marbles. Style, Color, and Decoration Transform your marble run into an aesthetic masterpiece with a palette of blocks, signs, and nature blocks. Color-customizable blocks (16 colors) Signs with custom text Nature blocks like grass, logs, leaves, and rocks Create, Share, Discover Build contraptions, run simulations, tweak designs, and discover unexpected interactions. Publish your tracks to the community with no limits, browse what others have built, and compete to beat the best time on Platformer level leaderboards.
