Update: Here are some of the ideas I have regarding the Diet Coke Rewards. I answer some questions for myself.

1.

Do all of the categories matter? If I get valid 12 pack codes, I end up

with 10 points. Valid 20 and 24 packs give me 18 points with no further

numbers to figure out. The bottle sized cap numbers give me 3 points

and STILL contains 14 characters! So no bonus to me for figuring out

which is which.

2. There is no cost, and no immediate penalty for

entering WRONG numbers and invalid codes. Since I all I need is an

email address, I could create multiple accounts to test this without

added cost.

3. For each slot in a code there are 34 possible

options (that’s because the letter O is always the number zero so

numbers 0-9 and 1 for each number of the alphabet). There are 14

characters, so, based on this alone, random chance isn’t impossible if

you set ranges and roll the dice. But can you do better?

4. I’ve

noticed overwhelmingly that Diet Coke numbers start with a number, and

contain no more than 7 numbers, and no fewer than 2. There are a few

exceptions, but I don’t need to hit every case out there to be able to

rack up many points. That means my odds have now improved. Additionally,

I’ve noticed that numbers tend to be grouped where they either start

with 1 or 2, then a certain letter grouping. Also, have you noticed that

numbers aren’t starting low? I haven’t seen many numbers starting below

1. I’ve also noticed that numbers are often repeated. Is there a

pattern to how many times they were repeated.

So, how do I test

this? One easy thing to test is the hypothesis that valid numbers don’t

start with 1. Using the numbers I have that are valid, I run a few tests

with 1 in the front. Heck, it doesn’t take too long to run zero through

5 to see if my guess is correct or not? As I gain more info, I start to

see more patterns.

5. Pattern matching, which is something the

brain does really well. One reason we humans are SO superstitious is we

see patterns, faces, and assign significance where there may or may not

be something of interest. A different way to look at the pattern is to

assign a number to each of my characters, and then see if any patterns

show up. I believe this sort of odd thinking is how people began playing

records backwards in order to hear devil sounds. One possible way to

assign values to number would as follows:

0 | 0 |

1 | 1 |

2 | 2 |

3 | 3 |

4 | 4 |

5 | 5 |

6 | 6 |

7 | 7 |

8 | 8 |

9 | 9 |

A | 10 |

B | 11 |

C | 12 |

D | 13 |

E | 14 |

F | 15 |

G | 16 |

H | 17 |

I | 18 |

J | 19 |

K | 20 |

L | 21 |

M | 22 |

N | 23 |

P | 24 |

Q | 25 |

R | 26 |

S | 27 |

T | 28 |

U | 29 |

V | 30 |

W | 31 |

X | 32 |

Y | 33 |

Z | 34 |

With these new ideas, I can run a few checks and see if I can learn anything new, or see any new patterns emerge.
