『「貪食蛇是一個產生於1970年代中後期的計算機遊戲。此類遊戲在1990年代由於一些小螢幕設備引入而再度流行起來，在現在的手機上基本都可安裝此小遊戲。」
在遊戲中，玩家操控一條細長的直線（俗稱蛇或蟲），它會不停前進，玩家只能操控蛇的頭部朝向（上下左右），一路拾起觸碰到之物（或稱作「豆」），並要避免觸碰到自身或者其他障礙物。每次貪食蛇吃掉一件食物，它的身體便增長一些，速度更逐漸加快，讓遊戲的難度漸漸變大。有些遊戲設計成四周牆壁皆可穿透，這有時比不可穿透牆壁更高難度。貪食蛇可以考驗個人的敏捷與反應。』

Snake
Snake is a calculator game created in the late 1970s. In 1990, Snake and other similar games were revived and became incredibly popular. It is now so widespread that the digital application could be easily downloaded by mobile phone.
In the game, the player controls a thin line which represent a bug or a snake. The player shifts the head of the snake in a certain direction to prevent the continuously moving snake from crashing into objects, its own tail or to swallow food. Every time the snake swallows food, it becomes longer and moves at a faster speed, making the game more difficult. The game is a test of one's reflexes.
