基于英语语言的知名游戏（可以归类为智商挑战题）：
anagrams
anagram定义为一个有着相同的字母的不同的词，例：
stop的anagram为：tops, opts, pots, and spot
类似的还有：
stool and tools
secure and rescue
anagrams就是多个词，具有相同的字母，但是意义完全不同，例：
Dormitory and Dirty Room
Elvis and Lives
The country side and No City Dust Here
Heavy Rain and Hire a Navy
Eleven plus two and Twelve plus one
还可以再长一点：
To be or not to be: that is the question, whether tis nobler in the mind to suffer the slings and arrows of outrageous fortune.
In one of the Bard's best-thought-of tragedies, our insistent hero, Hamlet, queries on two fronts about how life turns rotten. (Cory Calhoun)

长一点：

再长一点：
