In TOKYO METRO, players take on the role of private investors looking to build up stations across Tokyo, speculate on train lines, and comprise a shared network to benefit multiple parties. The core of the game is built around worker placement, which opens up three possibilities:

* Walking and riding trains across the Metro map, in order to build new stations at advantageous locations for income when trains pass through.

* Investment into train lines, either by purchasing stock and becoming a shareholder in the line, or by speculating on a train line you do not own stock in, in order to potentially double your speculation.

* Build up your available actions, by purchasing more action discs, purchasing discarded action cards for personal use, or gaining tokens for a specific use.

With route planning, investing, speculating, area control, and a real replication of the Tokyo area, TOKYO METRO brings a heavy economic twist to the TOKYO series!
