Angry Birds: Knock on Wood

Angry Birds: Knock on Wood is a board game based on Angry Birds that was released in May 2011 by Mattel. It is a game that enables players to create various structures that other players must attempt to knock down.

The contents of Knock on Wood include three Birds (Red, Yellow, and Black), four Pigs (Normal, Armor, Mustache, and King), fourteen wood blocks, 56 mission cards, and a single slingshot. All of the items are made of plastic.

Gameplay
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 wood blocks, 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 are pre-determined, 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.

Trivia

 * Knock on Wood is said to be the first set of a series.
 * Although the birds in Knock on Wood are in different orders and have different appearances, they have all the same properties as each other.
 * While in the video games the birds appear to have no limbs at all, the bird pieces in Knock on Wood have tiny wings on their sides.
 * Knockoffs of the game exist, and include different birds, pigs, and slingshot than the official release. These are distinguishable by pigs with molded faces (instead of stickers) and lacking the Mattel logo or the "Knock on Wood" title on the box.
