Scooby Posted February 3, 2008 Share Posted February 3, 2008 well it's just got mine wrong twice! Having said that, we got this ages and ages ago via email and we couldn't work it out Quote Link to comment Share on other sites More sharing options...
Eyren Posted February 4, 2008 Share Posted February 4, 2008 It'll be some mathematical pattern or combination of patterns, like, if a number is divisible by nine, then when you add together all its digits until you reach single digits, the result will always be 9. Try it! Create a sample number: 1782 x 9 = 16038 1 + 6 + 0 + 3 + 8 = 18 1 + 8 = 9 :D P.S. - aha, I was on the right track with the above! I tried the 7-up game twice, and my two sets of numbers at the final stage were 1782 and 2358. See anything in common?? Basically the smaller number you end up with by subtracting your two shuffled numbers will always add up to 18. Given three numbers that add up to less than 18, it's not hard to work out the fourth!

Ziggy Posted February 4, 2008 Share Posted February 4, 2008 My two final sets also add up to the same thing, but not to 18... they add up to 9 Quote Link to comment Share on other sites More sharing options...
Eyren Posted February 4, 2008 Share Posted February 4, 2008 Maybe that's why you're not allowed zero as your "secret" number - it prevents the program from telling the difference between sets of numbers that produce 9 and sets that produce 18...
