Digital / physical play: translate one rule across materials

Define a small interaction with one rule: sort a set, reveal a message, build a sequence, or choose a route. Make the first version on a screen. Record what the interface handles automatically, including timing, duplication, memory, feedback, and reset.

Translate the same rule into paper or physical objects. Do not imitate the screen. Decide who now performs each automatic action and how a participant knows the current state. Materials introduce weight, distance, wear, sound, and social negotiation.

The third version returns to a digital format. It must preserve one useful quality discovered in the physical test. This can be a visible history, a slower commitment, shared control, or a productive limit.

Critique compares the rule across versions. Which part remained stable? Which part depended on the medium? What did a participant learn through action that an image of the result would not show?
