Core gameplay
Blocks drop once every four seconds. You may reposition them any time before they lock. Rows clear automatically when full. No penalty for slow placement. Game ends only when you choose to stop.

Level and content structure
No levels or endings. You start and stop at will. The game does not track session length or rows cleared.

Visual and user experience
Dimmed screen brightness simulation (reduced contrast). Large block sizes suitable for tired eyes. No moving advertisements or pop-ups.

Features
An exit button closes the game immediately without confirmation. No pause function needed because dropping stops when no input is received.

User value
Designed specifically for low-energy periods. No challenge or failure state. Pure arranging activity.

Usage scenario
Late evening just before turning off the computer.
