Orbricks Toppler

A 3D physics puzzle you play right in the browser: remove the blocks, keep the ball on the platform, and don't let it topple — across a run of escalating worlds.

The premise

One rule you understand in a second: remove blocks, keep the ball balanced. A ball rests on a stack of blocks on a floating platform. Click a block to remove it — but pull the wrong one and the ball rolls off and topples. The fewer clicks you use, the better your score.

That single, legible goal is the whole design bet: easy to grasp, hard to master, and satisfying to watch fail. Streaks and a per-level timer turn "solve it" into "solve it cleanly."

Game & level design

Difficulty comes from the materials, not from hiding the rules. Each block type changes how a stack behaves, so a level is really a little balance problem you read before you touch it:

  • Wood — standard block; the baseline you plan around.
  • Stone — heavy; shifts the center of mass when it goes.
  • Ice — slippery; the ball won't sit still on it.
  • Metal — fixed; can't be removed, so it anchors your plan.
  • Lava — deadly; clear it before the ball ever touches it.

Worlds escalate by combining these — introducing one new pressure at a time so each level teaches the next.

Physics & implementation

The game runs a real-time rigid-body simulation with Cannon-es driving the physics and Three.js rendering the scene, populated with GLB world models — rocks, plants, and props that make each level feel like a place rather than a test rig.

The engineering challenge is trust: a physics puzzle is only fair if the simulation is stable and readable. Tuning mass, friction, and the "is it settling?" check so a topple feels earned — never like the engine cheated — is where most of the craft went.

Plays anywhere

Desktop uses click-to-remove with drag / arrow keys to orbit and tilt the camera and shift + arrows to zoom. On touch, it's tap-to-remove, drag to look, and pinch to zoom — the same game, mapped to the device in your hands.

Reflection

Orbricks is my proof that "playable in one click" is a feature. Shipping a real 3D physics game to the open web — no launcher, no download — forced hard calls about performance and clarity, and it's the project people most want to try rather than read about. So: go try it.
