Fibble: daily word game

Fibble is a daily word puzzle that plays like Wordle until you notice the clues cannot be trusted. You still guess a hidden five-letter word and still get green, yellow, and gray feedback, but exactly one tile in every row is lying to you. The real work is not recalling vocabulary, it is figuring out which clue in each row is false and reasoning past it to the true answer.

What is Fibble?

At its core, Fibble is a five-letter guessing game. You type a word, submit it, and the tiles light up in the familiar scheme: green means the right letter in the right spot, yellow means the letter is in the word but somewhere else, and gray means the letter is not in the word at all. If you have played Wordle, none of that is new. What is new is the rule that changes everything. In each row you submit, one and only one of those five tiles is lying. A green might really be a gray, a gray might secretly be a yellow, and it is on you to work out which one.

That single twist turns a vocabulary game into a deduction puzzle. Because you can never take a whole row at face value, you start cross-referencing rows against each other, looking for contradictions that give the lie away. If one guess marks a letter absent and another quietly implies it is present, one of those tiles has to be the liar, and spotting that tells you something real. Fibble hands you eight guesses instead of the usual six, and it opens with a provided starting word to give you a foothold before the lies begin.

To help you keep track, Fibble lets you flag tiles: mark a tile as one you believe told the truth, or as one you suspect is a liar. That bookkeeping matters, because holding several rows of half-trustworthy clues in your head at once is where the game gets hard. The puzzle is less about knowing obscure words and more about disciplined elimination, treating each row as a claim to be tested rather than a fact to be recorded.

There is a fresh puzzle every day, and you can also go back and play past Fibbles from earlier dates. The daily puzzle resets at midnight in your local time, so a new mystery word waits for you each day. If one puzzle a day is not enough, there is also an unlimited mode for endless rounds. The feel is quiet and analytical rather than flashy: a small grid, a familiar palette, and a rule that makes you second-guess every square you see.

How to play Fibble

Open Fibble at fibble.xyz in your browser.
Start from the provided opening word, or type any valid five-letter word as your guess, and submit it.
Read the green, yellow, and gray feedback, but remember exactly one tile in that row is lying.
Flag tiles as you go: mark the ones you trust and the ones you suspect are false.
Compare rows against each other to find contradictions that reveal the lie, then narrow down the true answer.
Keep guessing within your eight rows until you deduce the hidden word.

Tips and strategy

Treat every row as having exactly one lie, no more and no fewer, and use that certainty as a constraint rather than a nuisance.
When two rows disagree about the same letter, one of them is lying there, which itself is a solid clue about where the deception sits.
Spend early guesses on letter coverage, since more raw information makes it easier to catch which tiles are dishonest.
Use the flag markers consistently so you are not re-deriving your trust judgments every turn.
Do not fully commit to a green until a second row supports it, because even a green tile can be the lie.
Take advantage of the eight-guess budget to spend a row purely on testing a suspected lie rather than racing to the answer.
