# Constraints - Device Ports

Date: 2026-07-21
Per user instruction.

- **No LLM** on device games
- **No actual talking / voice I/O** (no mic, no TTS, no voice rec)
- Pure mechanics: grid, dice RNG, terrain, counters, procedural seed, visual expressions only
- Pixel Petz Corgi researched as FORM FACTOR only (screen-face + sprite expressions), not voice feature.
  Our version = deterministic pixel faces (100+ sprite states) + beeps/chimes, no speech.
- Keep Paper Apps DNA: pencil + d6 + lines/circles translated to digital tiles + buttons
