Core gameplay
Blocks fall at a slow, fixed speed. Row clearing removes blocks. No scores, no timers, no speed changes. The game runs entirely without storing any data beyond current session state.

Level and content structure
Single endless mode. No levels, no progression unlocks. Same speed from first block to final block.

Visual and user experience
Monochromatic colour scheme (greys only). Block borders are solid black. No text except Pause and Resume.

Features
Game closes without saving any session data. No prompts for permissions or network access.

User value
Minimal distraction. No long-term commitment or high score pressure. Suitable for users who wish to avoid all performance tracking.

Usage scenario
Airplane mode environments or places without internet service.
