Gamemap selection can be found in the game settings. You have three options to choose from: a live map, a static map and a 360° image map. Click the relevant map-icon, and choose the picture you want to use as your gameboard from your computer archive. If you don't have a picture of your own, you can use one of Seppo's default map pictures. When you have the picture ready, scroll down and save your image.
You can change your gameboard at many times you want. However, changing the game board from a live map into a static map will leave the exercises in one stack. You can drag the exercises apart and place them where you want them to be.
