What Mathler Is#

Mathler is a daily maths puzzle where the target number is shown up front and the hidden six-character calculation that produces it is what you guess. Every guess must be a valid expression that actually equals the target — you can't probe with arbitrary maths — and colour feedback (green for right-character-right-spot, a yellow-orange for misplaced, grey for absent) walks you to the exact hidden form in six tries.

It was created by Daniel Tait, the indie developer also behind Sumplete and CrossWordle, in early 2022 — weeks after Nerdle's January launch. His puzzle games were later acquired by Hey, Good Game, the studio that now runs it; the game also appears on AARP's games portal. It remains free in the browser, with an official archive of past puzzles and unlimited-practice modes.

How to Play Mathler#

Read the target, then build a guess that equals it. Order of operations applies — multiplication and division before addition and subtraction — so 1+5*10 is 51, not 60, and half of Mathler's difficulty is PEMDAS discipline under pressure. Standard Mathler is six tiles; an Easy mode shrinks the board, while Hard and Extreme grow it to eight tiles with more operators (and, in Extreme, feedback so stingy it only confirms greens). Exact mode details shift over time, so check the site's own menu for the current lineup.

One rule worth knowing before you rage at a near miss: Mathler auto-rearranges commutative guesses. If you type 2*3+10 and the answer is 10+3*2, the game recognises the equivalence — the same courtesy Nerdle's win rule extends, and the same maths our solver's commutative handling is built on.

Mathler vs Nerdle#

What the two share

Six guesses, colour feedback, one shared daily puzzle
Every guess must be mathematically valid
Order of operations (PEMDAS) governs everything
Commutative rearrangements of the answer are honoured
Free in the browser, with share-your-grid culture

What changes

The target is GIVEN; you hunt the calculation — Nerdle hides both sides
No equals sign on the board (the '= target' is implicit)
Standard board is 6 tiles to Nerdle's 8
Misplaced tiles go yellow-orange, not purple
Difficulty comes as modes (Easy to Extreme) rather than sibling games

Mathler is the most natural second game for a Nerdle player — close enough that your opener instincts transfer, inverted enough to feel fresh. Constraint-thinking matters even more here: knowing the target prunes the space before your first guess, the way knowing the equals-sign position prunes Nerdle. If that kind of reasoning is your idea of fun, our guide to Nerdle's hidden rules is the same pleasure in essay form — and today's puzzle is the gym.

Our rating:

Sharpen up before you switch. The deduction habits transfer: open with an information-rich guess, read the feedback, eliminate hard. Practise the loop on today’s NerdleBuddy puzzle or let the Nerdle solver suggest a next guess from your current feedback.

Frequently Asked Questions#

How is Mathler different from Nerdle?

Mathler shows you the answer and hides the calculation; Nerdle hides the entire equation, equals sign and all. Mathler's standard board is also shorter (six characters to Nerdle's eight) and it marks misplaced characters yellow-orange where Nerdle uses purple. The six-guess, valid-maths, colour-feedback core is identical.

Does Mathler use PEMDAS?

Yes — multiplication and division evaluate before addition and subtraction, exactly as in Nerdle. Forgetting that is the most common way to burn a guess, because every guess must equal the day's target to be accepted at all.

What happens if my guess equals the target but isn't the hidden calculation?

It's a legal guess and you get full colour feedback from it. And if your guess is a commutative rearrangement of the actual solution, Mathler rearranges it and counts the win — you're never punished for writing 10+3*2 when the answer was 2*3+10.

Is Mathle the same as Mathler?

"Mathle" gets used loosely around the web for maths-Wordle clones in general, and a few small games have used it as a name. Mathler — with the r, at mathler.com — is the specific daily find-the-calculation game created by Daniel Tait.
