Periodle, is a word guessing game inspired by Wordle. But instead of guessing a 5-letter word consisting of any of the letters from A to Z, you have to guess a word spelled from 5 elements of the periodic table from Hydrogen to Oganesson. Words you can enter can thus vary in length from 5 to 10 letters, as long as they can be spelled from elements of the periodic table and are valid English words.

Each day there is one word to guess which is the same for everyone playing on that day. As some of my previous projects, this game runs on German time, which may be different to your timezone. Words may thus not change at midnight, but on the plus side, everyone gets the same word at any time.

The word to guess is selected from a manually filtered list of over 1000 words, which vary from 6 to 10 letters. 5-letter words were excluded here.

How To Play
If you already know how to play Wordle, skip to the "What are orange letters?" section below.

Each day you have 8 attempts to guess a word and once you make a guess the elements will turn gray, orange, yellow or green. A gray element does not appear in the solution. If an element shows up yellow, then it appears in the solution but at a different position. If an element turns green, it is in the solution and it is at the correct position. Once you guess the correct word, all letters will be green.

In this example, the solution is S P Ra Y Er. In the guess C O P P Er, both carbon and oxygen are not part of the solution and thus show up gray. Phosphor is in the solution, but at a different position, the first one shows up yellow. The second phosphor shows up gray, as the solution only contains one phosphor. Erbium however, is at the correct position and will thus shows up green.

Please keep in mind that these colors may be different if you have changed the color theme. This description currently doesn't dynamically adjust to with the color theme.

What Are Orange Letters?
While Wordle and most of its clones only have gray, yellow and green letters, Periodle introduces orange letters or orange elements. When an element is highlighted orange, it is contained in the word to guess. But the element does not appear in the solution itself.

Here the solution was Pr Ac Ti C Al. In the guess P I Ra C Y, carbon is at the correct position and shows up green, while yttrium is not part of the solution and shows up gray. While phosphor and iodine are not part of the solution, the solution contains the letters P and I, thus those two show up orange. Radium is not part of the solution either, but the letter combination Ra shows up between promethium and actinium.

This way, if a single letter element shows up gray, it does not only mean that this element is not part of the solution, but that any double letter element containing this letter can't be part of the solution. In the first example carbon shows up gray, thus Calcium, Copper, Chlorine and many more, cant be in the solution either, otherwise carbon would have shown up orange. In such a case, those elements also show up gray in the periodic table keyboard.

Feedback And Discussions
For feedback or discussions of the game, you can go to the Discord Server. Just make sure to mark any hints for the current word as a spoiler. You can discuss older words in whatever way you like, as they change for everyone at the same time. Alternatively, you can send me feedback in an E-Mail to joshua@heptaveegesimal.com.

Games played in practice mode do not count towards your statistics!

Instead of the normal periodic table of elements, you can alternatively try an alphabetically sorted table of elements. This may be useful if you are less familiar with the periodic table, as this makes it easier to see which combinations of letters are possible in this game. For the true Periodle experience, it is recommended not to use this setting.

Alphabetic Table

Do you know a word in a different language that would be a good guess? This option will allow you to guess words from any of the languages listed below, not just the selected one. Words from other languages won't be the solution, but they might help you to get more information, if you are otherwise stuck.

Guess Any Language

When an announcement happens, the news page will open when you visit the page. If you do not wish to receive these notifications, you can turn them off here.

Automatically Open News Page

If someone sends you a link to a word that is not part of the word list (which could just be a nonsensical combination of elements) and this setting is on, a warning will be displayed. If you get an unlisted word, you will still be able to guess it for that game, but it might not be a plausible word. Note that this option does not warn you for links to obscure words that are part of the word list.

Warn For Unlisted Words

Select the language you want to play the game in. You can play the puzzles of multiple languages on the same day too. The daily words are uncorrelated between languages.

If you don't like the default look of the game or if you are struggling with distiguishing the different colors or want a bit of an extra challenge, here are some alternate color themes for you to pick from.

With your currently selected theme, the game will look like this (Black, Orange, Yellow, Green from left to right):

Sorry About Yesterday
Yesterday was an April Fools' joke, element 119 and 120 have not yet been discovered and neither will they have those names.
This site is still up, so you can replay this version, although you will only be able to play in practice mode. In addition, this site will no longer receive updates.
You can go back to the normal game Here!
Elements 119 And 120
Periodle celebrates the recent discovery of the two new heaviest elements: Expandium 119 and Joshaium 120. 119 bringing us the first new element discovery after over 10 years (Tennessine was first announced in 2010, but only officially received its name in 2016) and also expanding the Periodic to its eighth row. Perhaps the biggest challenge of this discovery being the decay behavior of these elements, no longer undergoing Alpha Decay (Emitting a 4He nucleus), but instead emitting a 12C nucleus and thus not matching any expected alpha decay chains. The synthesization has likely already succeeded throughout many past attempts, with the elements likely just falling under the radar.
Starting today, these two new elements can now be used for your guesses in Periodle!
Free Play And Word Links
Probably the largest update yet.
Alongside the daily word, you can now play an arbitrary amount of words in practice mode. These practice mode games do not count towards your statistics, you can mess around in these in whatever way you like without it effecting your statistics. On top of that, if you want to challenge someone to a specific word you can now go into setup mode, where you can enter any word that can be spelled with five elements and get a link to that word. Those links will then start the game in practice mode and with your specified word.
This News Page
Added this News Section!
Future updates to the game will be announced here. This page will show up whenever there is something new. If you don't want this page to show up, you can disable it in the settings. All news below here, I have added retroactively.
Color Themes
Added various color themes to make the game more accessible to anyone who is colorblind. Although some themes are more intended as a challenge instead of serving as accessibility. This reintroduces the Alpha Color Theme I used during early development, which is probably worse for accessibility.
German Periodle
Added a German version of the game.
Game data is now stored using local storage and no longer uses cookies.
The language can be changed in the settings, both puzzles can be played independently each day.
Start of this game with day 0 of course. This was a slightly chaotic start due to the very incomplete word list, which got expanded a few hours later.
