Endless Mode is a game mode that allows players to work on their cities without the possibility of Game Over. In order to expand the city, players must reach milestones by achieving a certain level of efficiency. Endless Mode can be accessed in two different ways: players can begin a game in Classic or Expert mode and when met with the Game Over screen, select “Continue in Endless Mode” to switch modes, OR by entering into Endless Mode from the start by selecting Endless on the mode select tab on the map card.
