Wordler is a browser based word guessing game accessible at wordler.org. Its primary function is to challenge players to identify a hidden word within six attempts. The game is a variation of the popular Wordle format, but it allows users to select puzzle lengths ranging from four to eleven letters, adding variability to each session. No download or account sign up is required to play, and a new puzzle is available daily. The tool includes several configurable settings. Players can choose the length of the hidden word, from four to eleven letters, and select from multiple languages, including English (US) and English (UK), to practice vocabulary in different linguistic contexts. A color blind mode is available, replacing the standard green and yellow indicators with orange and blue to improve accessibility. The game provides clear visual feedback: green indicates a correct letter in the correct position, yellow indicates a correct letter in the wrong position, and gray indicates a letter not present in the word. The on screen keyboard also grays out letters that have been eliminated, helping players track their guesses. A typical gameplay session begins with the player entering any valid word of the chosen length. The color hints from each guess inform the next attempt: green letters are locked in place, yellow letters are repositioned, and gray letters are avoided. The player has six total attempts to deduce the secret word. The interface is straightforward, with empty boxes representing each letter slot, and the keyboard below showing available characters. The game is designed to be learned quickly, with no complex instructions needed beyond understanding the color system. Technically, Wordler runs entirely in a web browser and does not require installation or registration. It is compatible with standard browser notification features, which users can enable to receive daily puzzle reminders. The website also lists similar games and presents quick facts about the game mechanics. The tool is intended for casual puzzle solvers, language learners, and anyone interested in a daily word challenge that can be customized in difficulty and language.
