Password analysis

The passwords on the Keitai series are 10 digits long.
Among them there are 6 variables, a pattern marker and a digit for the checksum.
The other two digits are normally just some random number, but it's easier to leave them at 0…
The 6 variables are:

• Password's [T]ype:
  • T = 0: Purchase
  • T = 1: Parent's money (Keitama)
  • T = 2: King's visit
  • T = 3: Gift (hidden items)
  • T = 4: Travel (Keitama)
  • T = 5: Trade (Keitama)
  • T = 7: 1, 4 or 5 but on the Akai
• Akai password type ([R]ed):
  • R = 0: Parent's money
  • R = 1: Travel
  • R = 2: Trade
• ID number ([A][B]):
  • T = 1, 4, 5 (Keitama) or 7 (Akai): AB = Tamagotchi's ID number (e.g., if the character is Mametchi [09], A = 0 & B = 9)
  • T = 2: AB = Tamagotchi's ID number (invitation for the phone app) or 44 (password for the Keitai)
  • T = 0, 3: AB = Item's ID number
• Additional info ([X][Y]):
  • T = 1: X = Money to receive (0–4), Y = Number of times parents have already been visited (0–3)
  • T = 4: XY = Travel destination
  • T = 5: XY = Item to trade

There are five possible [P]atterns. The second digit always dictates the pattern:

P = 0 or 1:
[X] [P] [0] [B] [A]
[0] [R] [T] [Y] [S]

P = 2 or 3:
[0] [P] [A] [R] [Y]
[X] [S] [0] [B] [T]

P = 4 or 5:
[0] [P] [B] [R] [Y]
[T] [X] [S] [A] [0]

P = 6 or 7:
[0] [P] [T] [A] [R]
[X] [B] [Y] [S] [0]

P = 8 or 9:
[R] [P] [0] [X] [B]
[S] [T] [Y] [0] [A]

The check[S]um is calculated by adding up all other 9 digits and taking the unit.
For example, if we want to buy a Katana [56]…
Using the most simple password pattern [0], first we would have:
[0] [0] [0] [6] [5] - [0] [0] [0] [0] [S]
Then we would calculate the checksum like this: S = 0 + 0 + 0 + 6 + 5 + 0 + 0 + 0 + 0 = 1[1]
Then, our final password would be: 00065 - 00001

Purchase

The purchase passwords always have a T value of 0.
The ID number will dictate the item that you will be able to buy.
The other variables do not matter, it's easier to leave them all at 0.

Parent's money

The T value will be 1 on the Keitama. On the Akai, T will be 7 and R will be 0.
The ID number must be the character you raised on the previous generation.
The X value will be the money you will get: X=0 : 500; X=1 : 600; X=2 : 700; X=3 : 900; X=4 : 1000
The Y value will be the amount of times your Tamagotchi has visited their parents. Keep in mind this counts the the current visit as well… in the first password Y will be 1, not 0.

King's visit

T will be 2.
The ID number will be your current character's in the code you get after donating the 1000 Gotchi points. However, in the password you must write in your Keitai to get the King's gifts, the value will always be 44.

Gift

T will be 3.
The ID number will dictate the item you will get.
Keep in mind this is only for hidden items, you can't just get all items for free using this type of password…

Travel

T will be 4 on the Keitama. On the Akai, T will be 7 and R will be 1.
The ID number will be your current character's.
The additional info value will dictate the destination: XY=67 : Europe; XY=68 : South America; XY=69 : Oceania; XY=70 : You knock on a jumping door! (Keitama, unused); XY=71 : Africa; XY=72 : North America.
This password will always be generated by your Keitai upon using a travel ticket. Its only purpose was to be used on the phone app, so you could see a photo of the trip…
It seems each character could have multiple different photos for the same destination, but I don't know the details…

Trade

T will be 5 on the Keitama. On the Akai, T will be 7 and R will be 2.
The ID number will be your current character's.
The additional info value would be the ID of the item you are offering on the password generated by the Keitai. The password you must input would have to use the ID of the item you will receive instead.
