How to play
Choose coastlines for four named islands, then draw the fifth. Your island previews at the center automatically.
Drag the map behind the fixed center reticle. Pinch or scroll to zoom for finer positioning. The size slider changes physical island size.
Guess submits the center and reveals the answer. Your first guess in each round is your official score. Practice again keeps your shape and size, but never changes that saved score.
