Build a town.
Make the numbers work.

Use your MFHS game login

Use the nickname and password your parent created. A parent who is already signed in can open a separate city for their own account.

Continue your city on another device

Your active city, named cities, and tutorial progress save to your MFHS login. Wait for “Saved across devices” before switching devices. Game nicknames and parent cities stay separate. If two devices save different progress, download a recovery copy and choose which version to continue.

Start with Learn to Play for a guided first town. The game supports a full desktop window; the smaller-screen controls remain available for review.

A parent must complete Cornerstone permission before a child plays. Keep personal information out of nicknames and city names.
