Dosun-Fuwari

Game Rules: Place exactly one balloon (hollow circle) and one iron ball (filled circle) in each room. Dark squares are fixed rocks. A balloon needs the top edge, a rock or another balloon directly above. An iron ball needs the bottom edge, a rock or another iron ball directly below. Room borders provide no support; stacks may cross them. Other cells stay empty; X marks are optional. Tap cycles blank → balloon → iron → X → blank. Hold (right-click with a mouse) cycles backward; drag paints the chosen state.

Game Rules: Dosun-Fuwari

Place one balloon and one iron ball in each room. Balloons float up, iron balls sink, and room borders alone cannot support either one.

Place exactly one balloon (hollow circle) and one iron ball (filled circle) in each room. Dark squares are fixed rocks. A balloon needs the top edge, a rock or another balloon directly above. An iron ball needs the bottom edge, a rock or another iron ball directly below. Room borders provide no support; stacks may cross them. Other cells stay empty; X marks are optional. Tap cycles blank → balloon → iron → X → blank. Hold (right-click with a mouse) cycles backward; drag paints the chosen state.

Frequently Asked Questions

How can I start solving Dosun-Fuwari?

Start with a cell directly under a rock. It can support a balloon there. A room boundary in the same position would let the balloon rise through it.
