You bring x amount of raw beef to iamkeeferz(streamer) , it's a collectors item for him. you choose a number between 500 and 1000, and the amount of rolls you get(amount of guesses) depends on your amount of raw beef. bring 5,000 raw beef and you will get 10 random numbers if you choose number 500 as your guess number. if you choose a number above 500, you will get less rolls, and since it's all random, it's stupid to choose above 501.
prices
if you guess 1 above(502 if you guess 501) you will get 1 month of osbuddy pro. this is the same as for one below
if you guess the exact number you will get 6 months of osbuddy pro
if the guy had chosen 501 in stead of 750, he would have gotten much, much more rolls and in doing so much much more chance of winning more osbuddy pro months
