What is Wordle Hard Mode?

In Wordle Hard Mode, every new guess has to respect what you already know: green letters must stay in place, yellow letters must stay in the word but move to a different slot, and grey letters are supposed to stay out of your guesses. It’s the same puzzle, just with stricter rules that push you to make better, more informed guesses.

How to use this Hard Mode helper

First, copy your current board into the helper: put any green letters in the “green” row, any yellow letters in the “yellow” row, and list the fully grey letters in the greys box. Then type the next 5-letter word you’re thinking of playing and hit “Check Hard Mode validity”. The tool will tell you whether that guess is allowed in Hard Mode and whether it makes good use of your remaining information.

If the guess is valid but doesn’t test many new letters, we’ll gently flag that and show a few alternative guesses that respect all of your greens, yellows, and greys while probing more fresh letters. You stay in control of the answer; we just help you avoid illegal or low‑information guesses that can cost your streak.

Wordle Hard Mode Helper FAQ

Does this tool solve Wordle for me?

No. The Hard Mode helper does not reveal the answer or force a particular guess. It simply checks whether your proposed guess follows Hard Mode rules and how much new information it gathers based on your current greens, yellows, and greys.

What rules does the Hard Mode checker enforce?

We enforce the practical Hard Mode constraints: green letters must stay fixed in their slots, yellow letters must stay in the word but move to a different position, and letters you have marked as grey should not show up again unless you’ve also marked them as green or yellow elsewhere. We also make sure your guess is a real word from the official Wordle guess list.

How are the suggested high‑information guesses chosen?

Suggestions are drawn from the same official Wordle guess list and filtered using your current board state. We favour words that respect all known greens and yellows while introducing as many new, untested letters as possible, so you get more information from a single guess.

Can I use this if I’m not technically in Hard Mode?

Yes. Even if you’re playing in normal mode, treating your guesses as if Hard Mode were on is a great way to build better habits. This helper can act as training wheels: you can quickly check whether a guess would be legal in Hard Mode before you play it.
