Jenga
The tower game as a 3D physics simulation. Slide a block out, place it on top, and find out how much the whole thing was leaning on it.
This is Jenga with a physics engine doing the judging. Blocks are rigid bodies with real friction and mass, the tower settles slightly every time you remove something, and a stack that looked stable ten moves ago has quietly shifted its weight onto one edge. You pull a block, put it on top, and keep going until it comes down.
What the simulation adds over the physical game is that you can orbit the camera freely and look at the tower from underneath, which makes the loose blocks much easier to identify. What it takes away is the feel of a block that is about to bind, so you will pull a load-bearing piece more often than you would at a table.
Controls
Drag to orbit the camera, click and pull a block, drop it on top
Tips
- Orbit underneath and look for daylight. A block with a visible gap on one side is carrying nothing and comes out clean.
- Pull slowly. The simulation transfers load as the block moves, and a fast pull drags its neighbours along with it.
- Middle blocks in a row of three are almost always the safe choice. The outer two are usually what the level above is resting on.
