Mathler rules and how to play
Mathler asks one question every day: what equation were we thinking of? You are shown the answer number up front, and your job is to type an arithmetic expression that reaches it. This page explains how a round works, what the tile colours mean, how the four difficulty levels differ and where to go next when you are done.
What is Mathler?
Mathler is a daily numbers puzzle in the Wordle family, published by Hey Good Game Inc. and playable for free in a browser. Instead of guessing a hidden word, you guess a hidden calculation: the game shows a target number, and every equation you submit has to evaluate to that exact number.
A round tells you nothing for free. Your six attempts show which digits belong to the hidden equation and which do not, so the puzzle is really about working backwards from arithmetic constraints. No account or app is required, and the site also runs a practice mode alongside the daily puzzle.
How to play Mathler
On the normal board you get six guesses of six characters, and the keypad offers the digits 0 to 9 plus the operators minus, times and divide. Enter an equation that equals the target number and press enter; if it is arithmetically valid, the game scores it.
Each character turns green when it is part of the hidden equation in the same position, yellow when it appears in the equation somewhere else, and grey when it does not appear at all. Position matters, so 3+9 and 9+3 can both be arithmetically correct while only one matches the hidden answer exactly.
Mathler applies normal order of operations to your expression, and commutative equivalents are accepted where the answer still lines up with the hidden equation. When you are stuck, that yellow-and-grey feedback is the whole game: it narrows which digits and which operators the answer must contain.
The daily puzzle, levels and practice
A fresh Mathler puzzle arrives once a day for everyone. Under the daily board you will also find an archive of past puzzles, plus a practice mode, so you can keep playing after you finish today's round. The four levels are separate boards: Easy uses five squares and one operator, Normal uses six squares, Hard expands to eight squares that include brackets, and Extreme returns to six squares with no yellow feedback at all.
The site keeps your completed puzzles in this browser, and it is free to use with no sign-up step. This page never shows a current answer, solution or spoiler for any puzzle, today's or yesterday's.

Frequently asked questions about Mathler
Is it free to play?
Yes. Mathler runs in the browser, is free to play and does not require a sign-up. The company behind it states the game is free, with no subscription.
How many guesses do you get in Mathler?
The Normal board gives you six guesses of six characters. The Easy board is shorter at five squares, Hard stretches to eight squares, and Extreme keeps six squares but removes yellow feedback.
Does the order of numbers matter?
It can. The game applies standard order of operations, and commutative answers are accepted, but the hidden equation has a fixed arrangement, so a valid sum in the wrong position still scores yellow rather than green.
Does the game give the answer away?
No, and neither does this page. Mathler only ever tells you which characters of your own guess were right; the target number is shown, but the equation behind it stays hidden until the round ends.
