Unlucky Dice (weighted)

The Weighted, Unlucky Dice

Designed for the April Fools contest, this dice is intentionally imbalanced. Unlike a standard "loaded" dice, this model uses a specific internal geometry to skew results toward the 1 and 2.

Statistical Analysis

We’ve included a probability chart based on several hundred test rolls. The data shows that the dice does not follow a standard uniform distribution. Instead, it favors specific faces based on the internal center of mass. About half of the time, the dice lands on either the 1 or the 2.

Key Variables

Our testing revealed that the bias is not absolute; it is influenced by the environment:

• Surface Material: Harder surfaces (glass, wood) produce more irregular bounces that can occasionally override the bias. Softer surfaces allow the weight to settle more effectively. At least we think so 😅.
• Throw Technique: The "style" of the toss matters. A high-arc roll with a quick rotation seems to randomize the result more than a low-friction slide.

Print Recommendations

To maintain the intended bias, the internal density must remain consistent with the design:

Infill: Use the provided 3MF file (given infill required)!

Material: We just tested standard PLA but other filaments should work as well.
