Write “MASH” at the top of the page
Choose categories to predict, such as spouse, house, car, job, number of kids, pet, and vacation spot
Under each category, list several possible choices
Pick one choice in each category as the final answer and mark it
Have one person secretly choose a number
Count the number of letters in “MASH” and in the marked choices
Use the chosen number to count through the letters and choices in a loop
Eliminate every choice landed on until only one choice remains in each category
Reveal the remaining choices as the prediction
Repeat for each category until all categories are completed
