+536 I will need someone to answer some of my questions in the answer pod below for this to work.
+536 You will probably figure it out but here it is!
You future number will be 29997.
+129899 HAHAHA!!!!!...I know it will come to 29997 !!!
I think I have the trick....although I'm not sure
You ask the person to pick a 4 digit number
Then...you add 9999 * 2 = 19998 to that number
This will be the "future number"
When they pick the next number.....you make sure that the number you pick and their second number sum to 9999
When they pick their final number......you do the same thing......you make sure that your final number and their final number sum to 9999
So....the future number is just their first number + 9999 * 2
Am I close ???
+536 Yes, You were very close, spot on infact!!!
I learned this in 3rd grade and it took me a week to figure it out!
+129899 One question.....you must be able to use numbers that have 3 leading 0s as possible four digit numbers????
Because....had I picked 9999 originally and then 9998....you would have had to use 0001 to get the first sum of 9999
And if I had picked 9997 as my last number.....you would have had to use 0002 to get the second 9999 sum......
Is this correct ???
+536 Yes, those would have been the nubers that I would have picked
You got it!!
+746 I think I know every answer that you and him chose had at least one 1 in it or more.
+16 I actually think the factor is that ProMagma was allowed to choose a number to add to the pile. If he didn't get to choose, I really don't know how one would get this trick to work. Unless mindreading over computers was developed. 
+655 This isn't really a trick right? It is just some subtraction and addition.......
It's like those pick a random number......now subtract you original number.
It just cancels out...
