How it works

This physical map of Southeast Asia labels 13 features with no country borders: five seas, five islands and peninsulas, and the Mekong, Irrawaddy and Salween rivers. Read the names first, then quiz yourself on them.

Read the full guide

Three rounds: seas, land, rivers

The seas and gulf go first, then Borneo, Sumatra, Java and the two peninsulas, then the three rivers. The Irrawaddy and the Salween run side by side down Myanmar: the Irrawaddy is the western one.

What the map leaves out

Luzon, Mindanao, Sulawesi, New Guinea, the Strait of Malacca and the Chao Phraya are not asked here, so check your class list.

  • Borneo is the one island shared by three countries: Indonesia, Malaysia and Brunei.
