Five dice in a glass box with a felt floor. Shake the phone and the dice fly; hold it still and they settle where physics puts them.
The box is the phone. Tilting, lifting and twisting all count.
A dense plate under one face moves the die's centre of mass towards that face, so the opposite face tends to come up. The die still weighs 4.5 g and looks the same.
The box shatters when the phone's acceleration (what the accelerometer reads, gravity included) stays above the limit for 25 ms. Slide to the right end for unbreakable glass.
Strongest so far: 1.0 g (at rest: 1.0 g).
Each throw starts with every die showing 1, shakes the box hard for 2 s (random accelerations to 50 m/s², rotations to 16 rad/s), then lets the dice settle. The loaded die from Setup takes part. Counts are per die; a fair die gives a flat column, and χ² has 5 degrees of freedom. A gentle shake is not a fair throw here or on a table: dice that are only slid keep their face.

The box is laid out for a phone held upright.
