Cut details
Goal: each piece within 48–52%.
Material weights
Each contribution is a share of the whole object’s modeled weight.

One line. Two pieces. Aim for 50 / 50.
The goal is equal weight. Equal-looking sizes may not be enough.
1 Inspect the materials
Hold Inspect to turn the object. Read the density chips: 10× means the same volume weighs ten times as much.
2 Drag, then release
Start outside the object and drag all the way through. Release to slice immediately. For a more deliberate cut, open the sliders below, adjust your line, then press Enter.
3 Watch the scale
The pieces land on the scale and the heavier side drops. Try again to practice, or move to the next object. Your first cut stays recorded.
Keyboard: arrow keys adjust the sliders; Enter slices the line. You can also use “Cut this line” in those controls. Escape clears the line. Hold Space or Enter on Inspect to turn the object. Animation can be skipped in the same controls.
Volume × density gives the weight.
After a cut, we seal the exposed faces and calculate each material’s volume on each side from the resulting 3D meshes. We add the material weights to get the two piece weights.

How do you get the volume of a curved shape?
The closed model is made of triangles. Each triangle and a shared reference point form a signed tetrahedron. Summing these signed volumes gives the solid’s volume, including the newly capped cut face.
V = |Σ a · (b × c) / 6|
Here a, b and c are triangle vertices relative to that reference point. We check that the two cut volumes sum to the original mesh volume. Scores use the generated mesh, rather than a real-world weight measurement.
The closer the weights, the higher the score.
A 50/50 cut earns 100. Our goal band is 48–52% on each side, which gives at least 96 points.
| Score | What it means | Next move |
|---|---|---|
| 99.50–100 | Excellent: each side is within 0.25 percentage points of 50. | Move on to a different shape. |
| 96–<99.50 | Goal reached: both pieces are within 48–52%. | A very small adjustment may improve it. |
| 90–<96 | Close: each side is between 45% and 55%. | Keep the angle; slide the line slightly. |
| 75–<90 | Uneven: the smaller piece is 37.5–45% of the weight. | Give the lighter side more of the object. |
| Below 75 | A big mismatch: one piece carries more than 62.5%. | Recheck the dense material before another cut. |
These are Cutle’s game bands. Readouts are rounded; the goal and labels use the full calculation. A poor first cut is still useful feedback for your next attempt.
Use the result to change your next cut.
Think about where the weight is concentrated, rather than only where the object looks widest.
- Find the dense part first.Use the material chips and Inspect. A small brass candle holder can carry much more weight than the wax above it.
- Move toward the heavier side.Keep the line parallel and move it into the heavier piece. That makes the heavier piece smaller and gives more material to the lighter one.
- Change one thing at a time.First adjust position while keeping the angle. If the heavy side switches, the better position lies between your last two lines.
- Check the material breakdown.Open “Cut details” to see each material’s share of the whole object on both sides. It explains why a larger wooden piece can still be lighter.
First cuts count. Retries help you learn.
Each UTC date generates five objects from a growing library of everyday templates. The templates are starting points: proportions, shoulders, necks, material boundaries, game densities and colors change with the date seed, so reloading does not reroll them. A new set becomes available at 00:00 UTC; an active cut is not replaced automatically.
Play all five for a full daily result.

All objects are stylized solid game models. Densities are relative game values; the scale indicates the calculated imbalance, not the weight of a physical object. Bottles and jars are solid game models: they do not simulate glass walls, empty space, or moving liquid. Twelve base templates currently generate many daily variants; twelve is not the number of puzzles. A template returns in a different form, and adjacent days use different templates.
Five finished. A new five to look forward to.
Here’s a little preview of your next set. Come back to cut them; for now, their weight balance stays a mystery.
