Gravitas

The classic ball maze as a collector’s object: the phone is the box.

Tilt maze

Six boxes in different materials —walnut, marble, brass, glass, ceramic and obsidian— with six handmade levels each. Played by tilting the phone, calibrated with a bubble level.

It also plays without sensors: finger, mouse, keyboard or gamepad.
