Same reason for many religions. People simply want to believe that by doing some pointless, random, and sometimes simple task a great divine being who - conveniently enough - cares about the individual to such an extent it will reward them, in one form or another.
When you compare the two, it's really not all that different.
Yes, most religions today deviate from their teachings, telling people "YOU WILL ALL DIE IF YOU DON'T JOIN US!!!" then extort money from them, or use their numbers to show off how big their religion is.
Similarly, Chain letters work at the same way, freaking people out to resend the mail. When the letter returns to the original sender, it gives him/her the satisfaction his plan is working, giving himself an ego boost.
Its like The Game.
