## What is Dosu Fuwa?

Can you master gravity?
Dosun Fuwari is a relaxing logic puzzle inspired by classic Japanese puzzle design. Place balloons and iron balls in the grid, use gravity to your advantage, and solve each puzzle through careful deduction.

Balloons float

Balloons are light, so they move upward. Find the correct position for each balloon based on the grid and surrounding obstacles.

Iron balls fall

Iron balls are heavy, so they move downward. Use their movement to eliminate possibilities and discover the solution.

Think before you move

Every puzzle can be solved through logic. There is no need to guess blindly. Study the grid, find the clues, and make your next move carefully.

Why you'll enjoy Dosun Fuwari

Unique gravity-based puzzle mechanics
Logic and deduction gameplay
Simple rules, challenging solutions
