original description: 心中選定一組號碼,在下個畫面出現時若出現在畫面中,則按下yes鍵,並未出現則按no鍵幾次按鍵選擇之後,終極密碼則魔術般出現在您眼前。 translated: Choose a set of numbers in your mind, and if it appears in the next screen, press the yes button, if it does not appear, press the no button. After several key selections, the ultimate password will magically appear in front of you.
