The underlying reward indexes are stable, but localized Easy Chat words differ by game language.

Tip: If a word looks missing in-game, re-check the Easy Chat category. The word may be in Abilities, Lifestyle, People, Battle, Types, or Feelings rather than a general Pokemon menu.
Tip: The reset attempt comparison is for convenience only. Every valid HGSS Trainer ID can unlock all three Primo eggs with the correct four-word phrases.

In Violet City, you have to get an egg from the Nurse. Rather then guess, you need to solve a code. After standing in front of the Nurse and choosing four words using Easy Chat, you don’t know which phrase(s) will lead you to a Mareep or if your choice will be refused. What makes it hard is that rewards 8, 9, and 10 corresponds to your Trainer ID via a specific mapping. If your number isn’t matched by the phrase, you won’t recieve any reward.

While most players dismiss it as luck, they’ll restart their save file over and over again until something work out. In reality, though, it’s just a simple math problem with predetermined results. To be clear: The system recognize your five-digit Trainer ID, which appears on your Trainer Card in full view. This is different than the Secret ID (which was assigned by the random number generator). Why does this matter? Because unlike the Secret ID, your actual Trainer ID are available to anyone who looks at your card anytime they want.

How to Get a Mareep Egg Using Math

There are no outside tools required to reveal it. Simply plug in your digits and calculator will convert the numbers into word sequence you’ll use when trying for a Mareep, Slugma, or Wooper. It is a quick process that eliminates countless hour of trial-and-error.

So when you’re resetting your number, you might want to know: Why do certain strings of letters and numbers come more easily to mind than others? Turns out there are three hundred fifty-one English words the game chooses from, divided up by category (e.g. These categories include People, Feelings, and Battle. Some categories result in a short word, one you’ll be able to type on the cramped screen with less chance of typo. Other categories give you longer words, ones that will be more difficult to spell correctly in the heat of the moment. With this tool, you can check how close you currently are to other numbers and see if a new number will result in easier-to-remember phrases. It won’t guess random numbers for you. It plots the possibilities, to let you decide what stays and what goes.

Another issue for a lot of people is version discrepancies. For instance, while Platinum operates one way, HeartGold/SoulSilver operate another. In fact, Platinum has no egg rewards at all. The calculator will automatically flag when this happens, preventing you from needlessly typing out phrases that won’t apply to your specific save file. That’s because the interface itself is identical between versions and it’s easy to forget what mechanics are even enabled.

For example, there are many trainers who wish to have an early electric type to combat the water type gyms. One popular Pokemon choice is Mareep because it’s available from eggs and is also electric. But chasing down a single pokemon egg isn’t mathematically supported, especially when that means restarting so many times over again. Every word chain are unique to each tier of rewards. With every id, you’ll be given a set of four different words per tier to match up. While this may lead to finding Wooper easy, Slugma may give you a hard time. That means deciding between which aspect you’d rather balance, typing convenience vs. Overall game goal? Do you need a certain typing advantage before hitting Kanto? Or do you just want the simplest path into the game?

This allows you to just input the words without having to remember what value goes into which ID field (i.e., that ID eight is a Mareep). The reference tables within the tool explain the egg to reward ID mapping so you don’t have to guess. It also makes sure the phrase follow strict rules and checks the checksum against an expected pattern to see if they match up. Any discrepancy will be highlighted by the tool to indicate where the issue is located.

It’s all about getting those eggs. To do that takes both precision and patience. The game asks you to type four words in the correct order without making any mistakes. One mistake, and your try are ruined. By preparing the phrase in advance, there is no need to calculate it on the spot. You enter the room cool, calm, collected, knowing exactly how to type the phrase. You see the egg, you hear the song, and off you go.

There’s more to this than the Pokémon within. There’s mastery of the system that guards its existence. It feels better to do the work then to just trust our luck.
