《憤怒鳥》是由芬蘭遊戲公司 Rovio Entertainment 開發的益智手機遊戲。該遊戲於2009年12月首次在 iOS 平台上推出。故事情節描述貪婪的豬偷走鳥的蛋，這樣的行為徹底激怒小鳥們，引發他們的報復行動。在遊戲中，玩家需要控制一群小鳥，將它們彈射到建築物上的綠色豬身上，以消滅它們。後來，遊戲也在 Android、PC、任天堂3DS 和 PS4 等平台上發行。

遊戲目標：玩家的目標是利用有限的機會，消滅遊戲場景中放置的所有豬。每個關卡的設計都不同，有些豬藏在堅固的建築物後面，有些則躲在易碎的結構物中。

操作方式：整體操作非常簡單，只需用手指在螢幕上拖動，然後放開，就能將小鳥彈射到目標位置。彈射的方向和速度決定小鳥的飛行路徑和落點。可以在彈射前調整彈弓的拉力和方向，以獲得更好的射擊效果。

不同種類的小鳥：遊戲中有多種不同種類的小鳥，每一種都有其獨特的特性和技能。例如，紅色小鳥是基本的彈射單位，可攻擊玻璃和木頭，但對牆壁的傷害較低。黃色小鳥能夠加速，適合針對木頭攻擊。藍色小鳥可以分裂成三個小鳥，可用來攻擊玻璃，但對木頭沒有太大損傷。黑色小鳥可以爆炸，適合針對混泥土攻擊。綠色小鳥可用來攻擊玻璃和木頭，但對混泥土的攻擊較弱。紅色大鳥的體型較大，攻擊力強，彈起後還可以碰撞其他物體。可以根據關卡的情況選擇適合的小鳥進行彈射。

計分系統：每個關卡都有一個三星評分系統，根據玩家的表現，可以獲得一到三顆星的評分。擊敗所有豬所需的彈射次數越少，得到的星星就越多。可以通過重新嘗試關卡來提高自己的得分。

總的來說，《憤怒鳥》是一款容易上手但又具有挑戰性的遊戲。其簡單的操作和多樣化的遊戲元素使得玩家能夠享受到無盡的遊戲樂趣。

"Angry Birds" is a puzzle mobile game developed by the Finnish gaming company Rovio Entertainment. The game was first launched on the iOS platform in December 2009. The storyline depicts greedy pigs stealing bird eggs, which infuriates the birds and leads to their retaliatory action. In the game, players need to control a group of birds and catapult them onto the green pig structures on buildings to eliminate them. Later on, the game was also released on platforms such as Android, PC, Nintendo 3DS, and PS4.

Game Objective: The objective for players is to use limited opportunities to eliminate all the pigs placed in the game scenes. The design of each level varies, with some pigs hiding behind sturdy buildings and others hiding within fragile structures.

Gameplay: The overall gameplay is very simple; players just need to drag their finger on the screen and release to catapult the birds to the target location. The direction and speed of the catapult determine the flight path and landing spot of the birds. Players can adjust the tension and direction of the slingshot before launching to achieve better shooting effects.

Different Types of Birds: The game features various types of birds, each with its unique characteristics and abilities. For example, the red bird is the basic catapult unit, capable of attacking glass and wood but with lower damage to walls. The yellow bird can accelerate, making it suitable for attacking wood. The blue bird can split into three smaller birds, useful for attacking glass but with minimal damage to wood. The black bird can explode, ideal for attacking concrete. The green bird can attack glass and wood, but its attack on concrete is weaker. The red big bird is larger in size, has stronger attack power, and can collide with other objects. Players can choose the appropriate bird for catapulting based on the level's circumstances.

Scoring System: Each level has a three-star rating system, and based on the player's performance, they can earn one to three stars. The fewer catapults needed to defeat all the pigs, the more stars the player receives. Players can improve their scores by retrying levels.
