How to play
What is Dosun-Fuwari?
Dosun-Fuwari is a Japanese Nikoli logic puzzle. The grid is divided into regions. Each region must hold one balloon (which floats up) and one iron ball (which sinks down).
What are the Dosun-Fuwari rules?
Each region needs exactly one balloon and one iron ball. A balloon must rest under a ceiling (grid top, a wall, or another balloon). An iron ball must rest on a floor (grid bottom, a wall, or another iron ball).
How do balloons float in Dosun-Fuwari?
A balloon is only valid if the cell directly above it is the grid top edge, a black wall, or another balloon. Balloons rise and stack beneath ceilings.
How do iron balls sink?
An iron ball is only valid if the cell directly below it is the grid bottom edge, a black wall, or another iron ball. Iron balls sink and rest on floors.
