Two to four players are required to play the game. The objective is to score a total of 1,000 points before another player does. To achieve this goal, one player must select one mission card, then the second player must assemble the structure using the appropriate number of woodblocks, Pigs, and bonus (yellow) items. Upon completing the structure, the first player then proceeds to use the slingshot to fire Birds into the structure. As with the game(s), the number of birds available is predetermined, as shown on the bottom of each card. If not all of the pigs are knocked down by the time the last bird is used, no points are accumulated. However, if the player does succeed, points are earned, with the value pictured on the top of each card. Harder structures will award more points, as easy ones will award fewer points.
