You know Dubrovnik is on the Adriatic coast, but you are unsure exactly where. A 500 km circle earns 3 points if it reaches the city. Shrinking it to 100 km offers 6 points, with less room for error.

Tap or click to place your circle. Drag the circle to move it; drag the map elsewhere to pan. Pinch, scroll, or use your trackpad to zoom.
With a keyboard, Tab to the map. Arrow keys pan, + and − zoom, Enter or Space places the circle, and Home resets the view. Tab to the radius choices and use the arrow keys to change size.
