看過『哈利波特 神秘的魔法石(Harry Potter And The Philosopher's Stone)』的人，應該對邏輯遊戲不陌生。
危險在前，安全在後，Danger lies before you, while safety lies behind,
我們之中有兩個可以給你援手，Two of us will help you,
但你得先把它們給喝進口，whichever you would find.
七個裡面有一個可以讓你繼續前進，One among us seven will let you move ahead,
另一個會將飲者送回門後。Another will transport the drinker back instead.
我們有兩個裡面只裝著蕁麻酒，Two among our number hold only nettle wine,
三個是殺手，藏在隊伍中靜靜等候。Three of us are killers, waiting hidden in line.
選擇吧，除非你想永遠在此逗留，Choose, unless you wish to stay here forevermore,
為了幫助你選取，在此提供你四個線索：To help you in your choice, we give you these clues four:
首先，不論毒藥藏得多麼滑頭，First, however slyly the poison tries to hide
你總是往蕁麻酒的左邊去走；You will always find some on nettle wine's left side;
其次，左右兩端的飲料都沒有毒，Second, different are those who stand at either end,
但你若想繼續前進，他們就不是你的朋友；But if you would move forward, niether is your friend;
第三，如你所見，七個瓶子個個不同，Third, as you see clearly, all are different size,
矮鬼或巨人裡面，都沒有死神在等候；Neither dwarf nor giant holds death in their insides;
第四，左邊第二與右邊第二乍見之下完全不同，Fourth, the second left and second on the right
嚐了以後才知道它們是無獨有偶。Are twins once you taste them, though different at first sight.
