How To Play

Each player receives a card that shows a Wonder of the ancient world., and a set of support buildings. The multiple stages of the wonder must, of course, be built from the ground up, while the buildings may be built in any order. Players have 4 worker meeples and a personal supply of resources, and there is a general supply. The resource supply bag moves from player to player to indicate whose the active player is.

You take one one of 4 actions per turn. You may Draw 3 cubes from the cloth supply bag and add one to your personal supply. The other two are added to the general supply. You may Take all resources of one type from the general supply. However, you may hold only 8 resources at a time in your supply, so if you Draw or Take more than 8 resources you must choose some to return to the general supply. You may Build a level of the wonder or a building by paying its resource cost from your supply. Your workers mark individual buildings as you build them, unlocking abilities. Finally, you may Sell pairs of matching goods to the supply in exchange for coins. Coins can be used as a wild resource, but also appear in some wonder costs. Resources used to build or sell return to the supply bag, and coins used return to the coin supply.

In games of 4 or more players, players may also trade. Trading occurs off-turn, that is, it can involve anyone except the active player. You may negotiate and trade freely with other players, but you must stop negotiating once you receive the supply bag and become the active player. The longer you spend on your turn, the more opportunity your opponents have to make deals.

The first player to complete his or her wonder wins!


  1. I am going to be quite bold here:

    Make sure your MSRP is $14.99 or less. Empire Engine was a nice stocking stuffer, or gift, at its lower “Why Not?” Price-point.

    I have played the previous v1.2 and it moved at a good clip. Very satisfied with where it ended up in the evening lineup. As a fast moving filler, or during eating, it is a great choice as it is a 1-handed game (someone holds the bag for you to draw from).
