Key to the City: London is a game for 2 to 6 players played over four eras. Each player aims to develop their London borough, using tiles representing well-known landmarks. On their turn, a player chooses one of five actions. They may used their wooden workers (keyples) to bid for, to generate resources from, or to upgrade the 57 unique and beautifully illustrated location tiles. Alternatively the player may pass, or cease playing in that era by setting off in their sailing barge along the Thames. The player accumulating the most victory points after four eras wins the game.

Key to the City: London has similarities to the award winning 2012 R&D game Keyflower, but offers the new challenge to games of connecting the tiles in their borough.
