Always keep your options open! Knowledge of all the ways to win will help you switch up your strategy should you find another Civ is about to take the victory and end your game.
Civ is a game with many viable strategies, and players can usually switch up their tactics to pursue an easier victory based on the tiles they have worked, opposing Civs around them and how the game is going. This Guide will show you how to win at the four primary victory types (Culture, Diplomacy, Domination, and Science), the fifth being survival until the year 2050, Time, which feels like a hollow victory, a failure to win at one of the actual goals. Civilization 5 offers you five different ways to win the game, and these have changed a bit as the game's expansions have been released. This Guide was written for gameplay features introduced in both the Brave New World and Gods and Kings DLC.
