Snow Sculpting
First, place the snow machine in your home and turn it on. After a period of time, the snow machine will produce snowballs. Tap the Collect button to obtain them.

Place the snowball sculpting bench in your home. Place the snowball on it to start snow sculpting.
During snow sculpting, chiseling at the prompt locations gives a chance for higher-quality snow sculptures. Chiseling at wrong locations or stay idle may result in a failed piece.
After sculpting, tap the Pick Up button to get the finished snow sculpture. Multiple players sculpting together increases the chance of obtaining higher-quality snow sculptures.
You can place finished snow sculptures to decorate your home. Some snow sculpture components can even stack on each other. Go explore yourself!
