How to use
Add your thumbnails
Upload your landscape and portrait thumbnails. If you have them, add the art-only versions too.
Add your logo, name and background
Upload your logo (a transparent PNG) or type your island name. Then add your 2048 × 1024 lobby background; the frame on its preview shows the part that stays visible.
Check every view
Switch between Lobby 4 slots, Lobby 5 slots, Discovery and Top 10 in the View section. Keep anything important out of the areas covered by buttons or cut off at the edges.
