Models.

Connection, Connexion, Plus, and K-Plus.

Tamagotchi Plus is the Japanese Name.

Tamagotchi Connection is the North American name.

Tamagotchi Connexion is the European name.

K-Plus, or Keitai Kaitsu Plus, are the Tamagotchi with fake antenna on them. They can communicate with certain Japanese cellphones and the DEKA Tamagotchi.

DEKA Tamagotchi are store display machines shaped like Tamagotchi used to provide a store (for gotchi points) interface without a cellphone.

Hanerutchi is just like a K-Plus, however it can only breed to another Hanerutchi. It's got characters based on a TV show called haneru-no tobira.

Batteries.

I hear a faint beeping from the Tamagotchi.

This is related to the screen movement of the Tamagotchi. It's nothing to worry about.

How long do the batteries last?

For the first released set (August), they last 3 weeks.

Afterwards, they usually last 3 months.

Connexions may last 7 or 8 months.

If I need to change the batteries....

After you change them, press B and select 'download'. The last saving point was the last evolution, connection, breeding, death, or restart.

Pause.

Tamagotchi (and most every other virtual pet that uses a "Pause" feature, but isn't just setting the time or putting it to sleep) last-action timer. This counts, in seconds, since your last action. So if your last connect, mating, evolution, ect was a few hours ago, well, it basically doesn't count it at all when you pause it. It's like those last few hours (excluding feeding, poops, ect) never happened. Thus, to preserve those hours, you need to do a connection, then pause afterwards.

Items.

What items can I get via Connecting?

Untangible items(not able for you to use): Cake, Flower, Scary Jack-in-the-box, poop, icecream (from the Old Lady and Old Man).

Connexions may also give a ghost (instead of Jack-in-the-box), or a diesese.

Connection can connect two babies (ShiroBebitchi and Bebitchi), however, when connected to each other, all you will get is a Poop. When an old person connects to them, they can get icecream.

Do I get to keep the items between generations?

No. Plus, Connection, and Connexion do not keep items.

Keitai-Plus units do keep items forever.

Connecting.

If a problem arises..

The units may be too far apart. Keep close together (7 or 8 inches or less).

Don't use a TV remote in the path of them. It's infrared can cause a failure.

Keep out of direct sunlight, connect inside a building.

Clean off the port at the top, any cloth will work.

Only one of you press the button to initiate.

How connecting works.

This is very simple. After you press B on one of the units on the connection screen, that unit is the benefitter (unless something goes wrong.. see above).

Failure results.

Tamagotchi may initiate in playing a loosing game with itself.

(When compatable) Tamagotchi may initiate mating process and end up with a baby (but the other unit doesn't).

Tamagotchi may put up it's away sign and visit the great beyond and then come back.

Breeding

Minimal age for connection breeding.

Assuming you want to do some time manipulation, the lowest times available for breedings:

36 hours after it is an adult, it can breed.

60 hours after it is an adult, the matchmaker might come.

At 48 hours after becomming an adult (usually, age 6), you are elligible for your tamagotchi to mate with another tamagotchi via connecting. They both must fit the requirement to be able to. After their friendship rating is at 4 hearts, they may have tamababies.

The male and female both get a baby. They will be the same gender.

Matchmaker?

If you are unable to find your tamagotchi another unit to mate with, you will see the matchmaker 72 hours after it has become an adult (usually age 7). Depending on your dicipline level, she will offer different partners. Partners with higher dicipline levels will make you elligible for a Kinakomotchi, and low ones will result in Marutchi.

Care.

What is the point of the training bars?

The training bars may somewhat determine the character you get, but they also serve a purpose in breeding. The higher your dicipline, the better chance at Kinakomotchi, in arranged marrages. The two types of training, praise and dicipline, also determine what characters you can get.

How long can I starve the tamagotchi before it gets sick?

After all of it's meters are down to 0, it takes about 15 minutes and it will get sick.

How many times can I starve my Tamagotchi before it dies?

Twice. On the third time in any lifecycle, it will die.

How do Tamagotchi get a cavity?

You can get them by feeding your tamagotchi too much candy.

Body and Heart?

Your Tamagotchi's needs are divided into two kinds: Body and Heart.

Body needs are food, it's health, and dicipline.

Heart needs are happyness, sleep, and praise.

How can I get certain characters?

Characters.

Kinakomotchi on the first generation?

If you have played with the unit before and had it die on you, when you restart it, you may be able to obtain a Kinakomotchi instead of a Marutchi as your toddler. The only time you may not get a Kinakomotchi is the first time you pull out the tab on the unit and play it.

Mametchi / Mimitchi.

These are not as hard as you'd expect, but they are much easier to get from a Kinakomotchi. Simply take great care of them, turn off the lights on time, feed them before they beep, clean up the poop alot, don't feed them too much candy in a row, ect.

Kuchipatchi / Memetchi.

Easy to get from a Kinakomotchi, take the exact care you would for a Mametchi/Mimitchi, but on the last day, ignore 1 dicipline, and let it's hearts empty. Next, when it's got it's back to you, feed it until it's full and continue taking excellent care of it.

Tarakotochi

Always keep it full, but neglect the happyness and only dicipline. Don't bother playing the games, just let him be a fatty McFatticus.

Hanatchi / Robotchi.

Starve it once, then keep it's happyness filled at all times possible, and make it beep at you for food.

Masktchi / Gonzarutchi

Starve it twice, simple, yes? Or if you have Marutchi, simply let it beep at you every time before you feed it/play with it.

Debug

What is debug?

Debugging a tamagotchi means you do a few steps in order to enable the debugging circut (used for product testing, taking pictures, and various other things).

Doing so voids your tamagotchi from repairs.

This enables you to get any character available on the unit, along with some they left over from testing. You may also speed up the lifecycle by pressing and holding "C".

Please read the following topic for more information about debugging.

Hyperspeed

When a Tamagotchi unit is in debug mode, you can access hyperspeed by holding down C. This quickly speeds up gameplay untill the next event (pooping, animations, beeping, ect).

Female unobtainable Characters

If you want to have a female of the unobtainable characters, hyperspeed the male untill it dies. You can eventually get a female.

Play normally, but with Hyperspeed.

Hold down C and hit reset. You'll get a normal looking egg, just set the time, press C, and the egg will hatch a random gender for you.

Using debug mode for breeding.

You can connect the unobtainable characters with normal units. However, sometimes the units may freeze up. Simply reset and download again to fix this.

Unobtainable characters can breed, but their friend-point gaining can be almost non-exsistant. It may take you several hours to get them to want to mate with another tamagotchi.

After an Unobtainable character mates, reset the debugged unit, or it will freeze when the parent tries to leave the baby.

Characters obtained via Hyperspeeding a normal egg will not have any trouble at all connecting or mating with normal units.

Keitai Kaitsu Plus Help

Since I do not have one of these yet, I can't offer much more then what's been said already. I'm going to assume they didn't make any major changes in how Debug Mode works (because you can debug them).
