Sumdog might be running slowly due to your school's network connection or your computer.
Here are some things you can try:
- Close other programs that are running in the background, and close any extra browser windows or tabs that you have open.
- Make sure that you are using the latest version of Flash and your browser is up to date. You can check these here.
- If your network connection is slow, you can ask your students to play against the computer, instead of against classmates or other users.
You may experience a poor connection if your school network uses a proxy to connect to the internet. Ask your IT administrator for help in improving your connection speed.
