Nerdle vs Wordle

Same daily-puzzle DNA, very different brains. Here's what your Wordle instincts get right about Nerdle, where the math rewrites the rules — and which game is actually harder.

Nerdle's counts are computed from the full ruleset (how we compute them); Wordle's are the widely published sizes of its curated answer and dictionary lists.

What Transfers From Wordle#

The feedback logic is identical. Green means right character, right spot; purple is Wordle's yellow (in the equation, wrong position); black is gray. If you can read a Wordle board, you can read a Nerdle board — including the tricky repeated-character rules, which work the same way.

Opening with information, not answers. Wordle players learn to open with letter-rich probes like CRANE or SLATE. The same thinking wins Nerdle: our exact computation over all 17,723 openers puts 52-34=18 on top — six distinct characters built from the most common digits, the Nerdle equivalent of a vowel-heavy starter (the full ranking).

Frequency thinking. Just as E and A dominate English words, digits aren't uniform in Nerdle — 1 appears in 14.8% of positions while 0 manages only 5.1%. Swap letter frequencies for digit frequencies and your intuition carries straight over.

What Math Changes#

Every guess must compute. Wordle asks for a real word; Nerdle asks for a true equation. That constraint is brutal and beautiful: knowing three characters often pins down the rest by arithmetic alone. A Wordle player deduces; a Nerdle player can sometimes solve.

Structure leaks information. The equals sign sits in position 6 in 59.3% of answers, numbers never carry leading zeros, and an 8-character frame only fits certain shapes. Wordle has no equivalent of "I know where the = is, so the right side is a 2-digit number." (Our strategy guide maps all of these hidden rules.)

The pool is enormous — and open. Wordle draws from a curated list of ~2,300 everyday words. Nerdle's 17,723 answers are simply all valid 8-character equations — nothing is hand-picked, and commutative twins like 12+35=47 and 35+12=47 both count as wins.

So Which Is Harder?#

With optimal play, Nerdle is the more solvable game despite the bigger pool: our decision tree finishes every one of the 17,723 answers in at most 5 guesses, averaging 3.05 — and 77.8% of answers fall in exactly 3. Published Wordle solver analyses land around 3.4 guesses on average, and human play runs higher in both games.

The reason is the math constraint: valid equations are so structured that each feedback pattern eliminates enormous swaths of the pool. For humans, though, Nerdle usually feels harder at first — arithmetic under pressure is a different muscle than vocabulary. Our hardest-answers analysis shows what the tough tail looks like, and every daily on this site carries a percentile difficulty rating so you can calibrate.

Frequently Asked Questions#

Is Nerdle harder than Wordle?

Under optimal play Nerdle is more tractable: every answer is solvable in at most 5 guesses (average 3.05 with our decision tree), because arithmetic validity prunes the pool aggressively. For most humans it feels harder at first — mental math under a guess limit is a different skill than word recall.

Is Nerdle made by the Wordle team?

No. Wordle was created by Josh Wardle and later acquired by The New York Times; Nerdle launched independently in January 2022 as a math-flavored take on the format. NerdleBuddy is an independent fan project, unaffiliated with either.

Do Wordle strategies work in Nerdle?

The core habit transfers: open with an information-rich guess, then eliminate. What changes is the material — digit frequencies replace letter frequencies, and arithmetic lets you deduce characters Wordle would make you probe for. Start with 52-34=18, the best opener by exact expected total guesses.

What do the purple tiles mean in Nerdle?

Purple is Nerdle's yellow: the character is in the equation but in a different position. Green means right character in the right spot, and black means the character isn't in the answer (or appears fewer times than you guessed).
