Find the Countries: Southeast Asia No-Borders Quiz

Mainland chains and island arcs

Southeast Asia has two very different-looking halves: the mainland around Thailand and Vietnam, and the island countries farther south and east.

Thailand gives you a mainland shape to learn. Indonesia turns the same quiz into an archipelago problem a few questions later.

How the no-borders map quiz works

A country name appears on a map with the political borders hidden. Click where it belongs. The coastline stays, so you still have some geography to work with.

Borderless mode is a good follow-up once the normal click map has become comfortable.

Tip: Pick out a coastline, peninsula or big country you know and judge the target from there.

Get the mainland comfortable first

Treat mainland and maritime Southeast Asia as two small maps until both feel easy.
