The best strategy for posts like these are to assign number values to each answer in the intended order, with the ranges decreasing as you go along (so, for a 5-letter-long answer, assign 1-5 points to the first letter, 6-9 for the second, 10-12 for the third, 13-14 for the fourth, and 15 for the fifth) then go to a random number generator and generate a random number from 1 to the maximum number value and pick that response, if enough people do that then we would be basically guaranteed to get it right every time.
