Anagram Help


When I cannot solve an anagram, I scribble the consonants close together in a cluster, instead of next to each other in a straight line. And then I scribble the vowels around them. And If I still can't get it, I mix them up a bit and try again. I find it helps a lot to solve the anagram quicker. Try it with 'pumotrec'. No, it's not 'rectum op'
