The Mini-Map is a window showing a small number of details of your immediate environment. You are the white/yellow dot in the center; green dots are other people. The Mini-Map rotates to face the same direction you are.

To see more, bring up the World Map by left-clicking the Map button (or the Mini-Map).

  • You are the white dot with the yellow circle around it. What you can see is within the gray triangle.
  • Drag the Zoom slider in the lower right corner to zoom in or out.
  • The World Map doesn't rotate: North is always up.

The World Map can tell you lots more:

  • Looking for other people? They're green dots, just like on the Mini-Map.
  • Looking for things to do? Pink stars show special event locations. Double-click on them for more information.
  • Looking for stuff or land to buy? Click the "Background" drop-down menu in the upper right corner, and choose "Objects For Sale" or "Land For Sale".

Notes:

  • The dots on the Mini-Map mean the same as they do on the regular map.
  • You can show or hide the Mini-Map with Ctrl-Shift-M.
  • If you see a green V pointing up or down, that means a person is up higher than you or lower than you.
