Jazle just asks you the name of a JavaScript library and restricts you to six choices. No two libraries are ever the same; every day brings a whole new one.

Guess The Hidden Library Name

The interface retains the minimalist style of the original Wordle, but the answers are drawn entirely from the JavaScript frontend and backend ecosystem. Players start with familiar names like React, jQuery, or Angular, then gradually dig deeper into less common libraries. After each entry, the system provides precise feedback: which characters are in the correct position, which are present but misplaced, and which do not exist in the target name at all. Many players begin with high-frequency library names to quickly identify common vowels and consonants. They then analyze the resulting letter patterns to eliminate invalid possibilities. If a letter is marked as non-existent, any library containing that letter can be immediately ruled out. Sometimes, short library names—only four or five characters long—make the puzzle easier to solve. However, long or obscure names can make those six attempts feel very tight. When stuck on the fourth or fifth guess, some players turn to search engines to cross-reference existing JavaScript library lists. This practice isn't forbidden, and it often helps players discover new names they hadn't heard of before.

Type Names Using Just Your Mouse

All interactions in Jazle require only a mouse to select cells and input characters. This simplicity allows players to focus entirely on the puzzle rather than learning controls. The clean interface, clear color-coded feedback after each attempt, and a fresh daily puzzle make it easy to turn the game into a habit. Jazle doesn't teach you how to code; it simply tests whether you remember the names of the tools you’ve used. And sometimes, that answer is harder than you think.
