So did I until I wrote my new education app 'Alien Anagrams'. It's a sort-of shoot'em-up, except you shoot bullets by correctly guessing anagrams.
Take the anagram in the screenshot above: "lseo". it took me a good few minutes to guess it, when I would have assumed a 4-letter anagram would take about 4 seconds. How many combinations can there be? But for some reason my brain keeps thinking of words like "leo's" or "selo"[tape]. Still, that's why I like playing this game; if you lose it's your own fault, and when the computer shows you the word, it suddenly becomes obvious what the answer was.
Give it a go (the first few levels are free, and they are challenging enough) and see how well you do.
