Calcle
Guess the daily hidden arithmetic equation.
Calcle is a daily math puzzle that borrows the guess-and-refine format of Wordle and applies it to arithmetic. The operators and the target result are already shown for you, and your job is to fill in the numbers that make the equation reach that result. You get five attempts, with color-coded feedback after every guess.
What is Calcle?
At its core, Calcle asks you to guess the numbers in an equation that equals the result shown to the right. The operator symbols and the target total are laid out for you, so the puzzle is about finding which digits belong in the blank number slots. You enter your guess one row at a time using an on-screen keypad, and once you submit a row the tiles change color to tell you how close you were. The loop is simple to pick up: guess, read the hints, adjust, and try again until you solve the equation or run out of rows.
Input is handled through a numeric keypad that shows the digits 0 through 9 along with a DEL button and an equals button. You can also type on a physical keyboard, using Enter or the equals button to submit a row and Backspace or DEL to fix a mistake. Because you only enter numbers, every guess is about placing the right digits rather than choosing operators.
The feedback follows the familiar three-color scheme, applied to the numbers you guess. Green means a digit is correct and sitting in the right position. Yellow means the digit appears somewhere in the equation but you placed it in the wrong spot. Gray means the digit is not part of the equation at all. Reading those colors carefully across your five guesses is the whole game, since each attempt should rule out digits and lock in what you already know.
When you finish, a Copy results button lets you share how you did, and the site includes a contact form for bug reports and comments. A fresh puzzle drops every day, and the live site shows a Next Daily Challenge button along with a New Game option. The game is free, needs no account, and runs in the browser. It also offers a dark theme and a high contrast mode, though those are display settings rather than separate ways to play.
How to play Calcle
- Open Calcle at calclegame.com in your browser.
- Look at the row: the operators and the result on the right are already given, so you only need to fill in the numbers.
- Enter your first guess by tapping digits on the on-screen keypad, then submit the row with the equals button or Enter.
- Read the tile colors: green for a correct digit in the right place, yellow for a digit that belongs elsewhere in the equation, gray for a digit that is not used.
- Use those hints to plan your next guess, keeping green digits fixed and moving yellow ones to new positions.
- Keep refining across your remaining rows until you complete the equation, and solve it within five attempts.
Tips and strategy
- Lock in every green digit and reuse it in the exact same spot on your next guess, since its position is already confirmed.
- Treat yellow digits as known-but-misplaced: they belong in the equation, so keep them in play and just move them to a different position.
- Drop gray digits entirely on your following guesses to avoid wasting a row on numbers that are not part of the answer.
- Use the given operators and result to do the arithmetic yourself, then check which candidate numbers could actually make the equation balance.
- Spend an early guess on a spread of different digits so you learn quickly which numbers the equation uses.
- With only five attempts, favor guesses that test the most new information rather than small variations of a guess you already tried.

Calcle FAQ
Is Calcle free?
Yes. Calcle is free to play in the browser and does not require an account.
How do you play Calcle?
Each row shows an equation with the operators and the target result already filled in, and you guess the numbers that make it reach that result. You enter digits on an on-screen keypad, and after each guess the tiles turn green, yellow, or gray to show which digits are correct, misplaced, or unused. You have five attempts to solve it.
Do you have to guess the operators in Calcle?
No. The operator symbols and the result are shown to you. You only guess the numbers that fill the equation.
When does Calcle reset, and is there an archive?
A new puzzle drops every day, and the site shows a Next Daily Challenge button. There is no visible archive of past puzzles on the page, so the focus stays on the current daily.
Is Calcle like Wordle?
It uses the same five-guess format and green, yellow, and gray color hints as Wordle, but you are guessing the numbers in a math equation rather than the letters in a word.
