Easy but Hard: How Pairdle Breaks Wordle's Bell Curve

Every daily word game ends the same seven ways. You solve it in one, two, three, four, five or six guesses — or you don't solve it. That's the whole outcome space. Which means you can describe an entire game, its difficulty and its personality, with seven numbers.

Wordle's seven numbers make a bell. Almost everybody lands in the middle.

Pairdle's don't. And when we finally sat down with our own player data, the shape that came back was stranger than we expected: players win Pairdle faster than Wordle on average, and lose it about five times as often.

That combination shouldn't be possible if "difficulty" is one number. It is possible if difficulty has a shape.

The four shapes

Pairdle ships three daily tiers, so this is really a four-way comparison — one Wordle, three Pairdles.

Look at Wordle first. Two bars carry the whole game: 38% of games end on guess three, 43% on guess four. Eight games in ten finish in that two-guess window. Almost nobody wins early — 6% get there in two, and winning in one is a lottery ticket. Almost nobody loses, either.

That is a bell, and it's a narrow one. Wordle is a game about being funnelled to the same place as everyone else, slightly faster or slightly slower.

Now walk left to right along the Pairdle tiers and watch the mass migrate. Standard's peak is lower than Wordle's and sits a guess earlier. Challenge's peak is lower again and its right side has thickened. Championship barely has a peak at all.

Here are all seven numbers for all four, side by side:

(Whole percents, so a row may not total exactly 100.)

The cleanest way to read that table is to find each row's biggest number — the single most likely thing to happen to you:

Wordle 43%. Standard 34%. Challenge 23%. Championship 20%.

That is the whole article in four numbers. In Wordle, nearly half of all games end the same way. By the time you reach Pairdle Championship, the most common outcome happens one time in five — and every one of the seven possible endings happens at least 6% of the time. There is no typical Championship game. There is barely a typical Pairdle game.

Wordle's two biggest buckets — guesses three and four — hold 81% of everything that happens. Standard's two biggest hold 55%, and they're guesses two and three: the peak is both lower and further left. Challenge's two biggest are guesses three and five — the distribution has split in half. One game concentrates its outcomes; the other three distribute them, more and more as the tier gets harder.

The number that gives it away

Here are the averages, on the same six-guess budget:

Read the first two rows twice. Pairdle's daily is faster on average than Wordle and loses five times as often. The average says "easier." The tail says "harder." Both are true, and they're true for the same reason.

Then look at the last two rows, which are the same trick in a different costume. Challenge and Championship are a tenth of a guess apart on average — 3.9 and 4.0, close enough that you'd call it a tie — and Championship loses half again as many games. Rank those two tiers by average and you'd call them equally hard. Anyone who has played both would laugh at you.

An average is a terrible summary of a game. It tells you where the middle is, and the middle is exactly the part of a daily puzzle nobody remembers. What you remember is the day it fell out in two, and the day your streak died.

Wordle mostly doesn't give you either of those days. Pairdle gives you both.

Why Pairdle splits

The mechanism is the board.

In Wordle, the answer is hidden in a space of thousands of five-letter words and you buy information one guess at a time. The feedback is fine-grained — five letters, three colours each — so almost every guess meaningfully narrows the field. You can't shortcut it, and you can't really get lost in it. That's why the bell is narrow: the game does the same thing to everybody.

A Pairdle answer is a six-letter word cut into three letter pairs — a FIRST pair, a MID pair and a LAST pair. Those pairs are drawn from a pool sitting face-up on the board, built from eight hidden six-letter words. Twenty-four tiles, all visible from the first second.

That visibility is the fast half. The answer isn't hidden in the dictionary; it's hidden in plain sight among 24 tiles. Some mornings you look at the pool and the word is just there — you see GA, RD, EN and you're done before you've really started. Nothing in Wordle can do that, which is why Wordle's one-and-two-guess bar is essentially flat and ours isn't.

The slow half is what happens when you don't see it. The pool doesn't only contain the answer's pairs — it contains enough raw material to spell a lot of real six-letter words, because it was built from eight of them. And Pairdle's feedback is coarser than Wordle's: you're getting signal on three slots, not five letters. So when recognition fails, you're left choosing between several genuinely plausible words with less information per guess than Wordle gives you. That's how a six-guess budget runs out.

Recognition or grind. The distribution is bimodal because the experience is bimodal.

The one-guess column makes the point on its own, with one caveat. Our simulation opens with the same word every day, so it wins on guess one only when the answer happens to be that exact word — the 0% is partly an artefact of the method, and real players who vary their opener do occasionally get lucky. But only occasionally, and that's the real point: in Wordle, a one-guess win is nothing but luck. There is no skill that produces it, because you're naming one word out of thousands with no information at all.

In Pairdle it's 6%, which is far too often to be luck. Those aren't lottery winners; those are people who looked at the pool and recognised the word before making a single guess. Wordle has no move that can do that, because at guess one there is nothing to look at yet.

The flip side is the loss column, and it's worth being precise about what makes a Pairdle loss different. Losing at Wordle usually means you got unlucky with a word family — you narrowed it to _ATCH and burned your last guesses on CATCH, MATCH, LATCH. Losing at Pairdle usually means the opposite: you had too many plausible candidates rather than too many similar ones, and three slots of feedback per guess wasn't enough to separate them before the budget ran out. One failure mode is a coin flip you keep losing. The other is a search you never finished.

This is also why the hardest Pairdle days are hard. When we ranked our ten most brutal puzzles, the culprit was almost never an obscure answer — it was a pool that spelled too many good alternatives.

Difficulty stretches the curve, it doesn't slide it

If the bimodal story is right, cranking the difficulty shouldn't just push the whole curve rightward. It should pull it apart at both ends. Stacked up as whole games, that's exactly what it does:

Championship is the purest version of the thing. It gives you one slot per position and no room for error, and it loses 14% of its games — fourteen times Wordle's loss rate. Half of all Championship games take five guesses, six guesses, or end in failure.

And yet it still ends 16% of games in one or two guesses — a larger early share than Challenge, and nearly three times Wordle's. The hardest thing we ship is also, more often than the easiest thing Wordle ships, over in two moves.

That's not a harder bell. That's a game pulling apart at both ends.

If you clear a Championship board, take the win seriously. Roughly one in seven of them beats you outright — fourteen times the loss rate of a well-played Wordle, which goes down about once in two hundred games. That gap isn't a matter of degree; it's a different order of thing. So if you finished one this morning, that wasn't luck and it wasn't routine. You're a word wizard, and you may quote us on it.

A methods note, including the embarrassing part

Two things you should know before you trust the chart.

The Wordle line is simulated. The New York Times doesn't publish a machine-readable guess distribution — the community numbers live inside WordleBot, behind a subscription. Its public data endpoint returns the day's answer and nothing else. So rather than launder someone else's scrape, we ran our own: every answer in the real Wordle answer list, played out with a fixed opener and a consistent strategy, six guesses allowed.

The check on that is whether it lands where reality lands. It does — the simulation averages 3.6 guesses and solves 99% of boards, which sits right on top of the community averages third-party trackers report from WordleBot. The shape matches too. Wordle turns out to be a narrow enough game that decent play and average play produce nearly the same curve, which is itself a fact about Wordle. That's the licence for putting it next to human data.

Our own data only counts from 8 August 2026, because before that our board was broken. Pairdle's generator is supposed to lay out 24 tiles from eight words: the answer plus seven decoys. A single defect meant it was throwing nearly all of them away and backfilling with meaningless letter pairs — the board carried the answer's own three pairs and almost nothing else. It shipped in December and we didn't catch it until August.

Which is exactly the problem, because a board with no decoys is a much easier board:

Before the fix, 42% of daily games ended in one or two guesses and 2% were lost. After it, that early share fell to 27% and losses more than doubled. The average moved from 2.9 to 3.2 guesses. One line of code, and the game got measurably harder — which is to say, it finally became the game it was designed to be.

We could have quietly started the chart in August and said nothing. But a distribution is only as good as the boards that produced it, and half this article is an argument about what decoy words do to a curve. Here's the natural experiment, run by accident, on ourselves.

Two smaller caveats, for completeness. The samples behind our numbers are modest — real players, but treat the exact percentages as a snapshot rather than a verdict. And our new players' very first board is a deliberately gentle practice round that never reaches these statistics at all, so if anything the early-win share here understates what a new player actually experiences.

What a shape is worth

There's a reasonable design argument that Wordle's bell is the correct answer for a daily puzzle. It's dependable. Almost everyone succeeds, almost everyone succeeds at roughly the same rate, nobody's streak dies on a Tuesday for reasons they can't explain. When we looked at why five letters is the right length, that reliability was the whole finding — five letters is where a word game gets real tension without regular heartbreak.

But dependable has a cost, and the cost is that very little is at stake in any individual day. If eight games in ten end the same way, the ending isn't news.

We didn't set out to build the flat curve; we set out to build a game where the board is visible and the deduction is about words rather than letters, and the flat curve is what that produces. It means Pairdle asks something different of you than Wordle does. Some mornings it hands you the answer and you feel like a genius for eleven seconds. Some mornings it hands you six plausible words and one budget, and you lose.

If you want to know which kind of player you are, the honest test isn't your average. It's how much weight sits at the ends of your seven numbers.

If you've only ever played the other one, here's how the two games actually differ — and Pairdle itself is free on the web, iOS and Android.
