Palindrome Tester

What is a palindrome? A palindrome is a word or phrase which reads the same forward or backward. Here are some examples: "radar", "Abba", "Madam, I'm Adam"

This little Flash movie let's you type in a phrase and then analyzes it to see if it is a palindrome. Spaces and some punctuation marks are ignored, as are differences in case. Therefore, "A man, a plan, a canal: Panama" is a valid palindrome.

To use the movie, just type a phrase in the 'Input' area, then click on the 'Test for Palindrome' button. The verdict will be displayed in the middle of the movie's display area.

Requires Shockwave Flash 4 Plugin (or later).

Some more example palindromes:
  • "Able was I ere I saw Elba"
  • "Pa made Ed a map"
  • "kayak", "Ada", "Glenelg" (a suburb in Adelaide)
  • the trivial cases of a blank, a single character, or a string of identical characters
