How to play

1. Choose a direction. In Contours → Terrain, read the line pattern and select a landform. In Terrain → Contours, inspect the tactile model and select its contour pattern. Changing direction starts a new ten-round session.
2. Choose one answer. Closed loops can mark a hill; inward hachures distinguish a depression; an elongated crest suggests a ridge; a pinched pass suggests a saddle; and bends into high ground suggest a valley.
3. Read the explanation. After every first choice, compare the stated clue with the picture, then choose Next. At round ten, finish to store one aggregate accuracy summary locally.

Compare slope spacing

In the separate slope strip, choose the side whose contour lines are closer together. This is only a relative visual comparison; there is no scale, contour interval or computed grade.

Touch and keyboard

Every answer is a native button with a focus indicator and at least a 44-pixel target. Tab moves among controls; Enter or Space activates the focused choice. On narrow screens, choices stack in one column rather than requiring horizontal scrolling.

Use the result correctly

Accuracy describes this simplified browser session only. It cannot validate compass skill, route choice, hazard awareness, map orientation or safe field navigation.
