Core gameplay
The well begins completely empty. No blocks fall automatically. Instead, you select from a list of three block shapes and place them anywhere in the well. Your goal is to form complete rows using limited placements.

Level and content structure
Eighty puzzles. Each puzzle gives a fixed number of placements (between 10 and 30). You must clear a target number of rows within that limit.

Visual and user experience
Block shapes are displayed as buttons below the well. Selected shape highlights in yellow before placement. No time pressure.

Features
An undo button is unlimited but resets the whole puzzle. A warning appears before reset.

User value
Removes falling speed entirely. Focuses purely on spatial arrangement. Suitable for users who find falling timers stressful.

Usage scenario
Rainy afternoons with a hot drink.
