In many ways 7 Wonders Duel resembles its parent game 7 Wonders as over three ages players acquire cards that provide resources or advance their military or scientific development in order to develop a civilization and complete wonders.

What's different about 7 Wonders Duel is that, as the title suggests, the game is solely for two players, with the players not drafting cards simultaneously from hands of cards, but from a display of face-down and face-up cards arranged at the start of a round. A player can take a card only if it's not covered by any others, so timing comes into play as well as bonus moves that allow you to take a second card immediately. As in the original game, each card that you acquire can be built, discarded for coins, or used to construct a wonder.
