🟩 Right symbol, right spot • 🟨 In the equation, wrong spot • ⬜ Not in the equation • A fresh daily equation lands every day
A nerdle game you can play right here, free. This is Daily Equation, an original GameOLL maths game. A hidden equation is waiting — eight symbols long, with one = sign buried inside it. You get six guesses to find it. Every guess must be a true equation, and after every guess the tiles change colour and point you closer. Green is the right symbol in the right spot. Yellow is close, but in the wrong spot. Gray is not in the equation at all.
Play the Daily Equation for the same puzzle everyone else gets today, and build a winning streak that grows day after day. Jump into Free Play for endless random equations, or warm up with Mini 6, a shorter six symbol version. No download. No sign-up. It works on your phone and your PC, and your stats save in your browser.

How to play Daily Equation
The rules take ten seconds to learn. The fun is in the detective work — part word game, part maths puzzle.
- Press Daily Equation for the puzzle of the day, Free Play for a random eight symbol equation, or Mini 6 for a shorter six symbol one. A fresh board of six rows appears.
- Type an equation. Use your real keyboard, or tap the digits and symbols on the keypad. On a keyboard, the star key types × and the slash key types ÷. Press Enter to lock the guess in.
- Every guess must be a true equation. The left side must really equal the right side, with exactly one = sign. If the game says your equation is not valid, the row is not used up. Just edit it and try another one.
- Read the colours. Green tiles are locked in. Yellow symbols belong in the equation, but one spot over. Gray symbols are out. The keypad colours itself too, so you always know which digits and operators are still alive.
- Find the equation in six guesses or fewer to win the round. Run out of rows and the game shows you the answer, so you learn it for next time.

The tile colours, explained
Every tile tells you one of three things. Learn to read them fast and the puzzle slows down in your favour.
| Colour | What it means | What to do next |
|---|---|---|
| Green | The symbol is in the equation, in exactly this spot | Keep it there in every later guess |
| Yellow | The symbol is in the equation, but in a different spot | Move it to a new spot in your next guess |
| Gray | The symbol is not in the equation at all | Stop using it, unless the duplicate symbol rule says otherwise |
Say the hidden equation is 12+34=46 and your first guess is 14+23=37 — a true equation, so it counts. The 1 and the + sign turn green, because each one sits in exactly the right spot. The = sign turns green too. The 4, the first 2 and the first 3 turn yellow: each one is in the answer, but one spot over. The second 3 and the 7 stay gray. One guess in, you know three symbols for certain, three more are close, and the shape of the answer is already taking form.
The duplicate symbol rule
This is the one rule that trips up new players, so here it is in plain words. A symbol only lights up as many times as it appears in the hidden equation. Green tiles are claimed first. Then yellow tiles are handed out, one by one, from left to right, until the answer runs out of that symbol. Any extra copies stay gray.
Look at that first example again. The guess 14+23=37 holds the digit 3 twice, but the hidden equation 12+34=46 holds it only once. So the first 3 turns yellow — it claimed the answer’s only 3 — and the second 3 stays gray. A gray tile does not always mean the symbol is out. It can mean you already found every copy of it. Keep that in mind before you throw a digit away for good. The same rule covers repeated operators: an answer with one + sign can only light up one + in your guess.
What counts as a valid equation
The game checks every guess with a real equation validator before it paints a single tile — the same checker that proved every hidden answer before it joined the game. A guess is refused, without using up your row, when it breaks any of these rules:
| Rule | What it means | Example |
|---|---|---|
| Right length | Eight symbols in the full game, six in Mini 6 | 12+34=46 is eight symbols |
| Exactly one = sign | One equals sign, with maths on the left and the result on the right | 1+2=3=4 is refused |
| The maths must balance | The left side must really equal the right side, with × and ÷ worked out before + and − | 2+3×4=14 balances, 2+3×4=20 does not |
| No leading zeros | A number cannot start with 0, unless the number is 0 itself | 01+23=24 is refused |
| No double operators | Two symbols in a row, like ++, are not allowed | 12++3=15 is refused |
| No division by zero | You can never divide by 0 | 12÷0+3=9 is refused |
| Whole divisions only | Every division must come out as a whole number | 10÷3+2=5 is refused |
| Numbers up to 999 | Every number in the equation is 999 or smaller, and hidden answers always end in a result from 1 to 999 | 25×4=100 is a classic shape |
The hidden answers are held to a fair standard too. Every answer in the bank was generated and then machine-checked: the equation is valid, the result sits between 1 and 999, and the left side always uses a two-digit number or two operators, so you never waste a game on a trivial sum like 1+2=3. Answers also never hide a lonely 0 term or a do-nothing ×1 — every symbol in the answer earns its place.
The swap rule: same equation, fair win
Here is a kindness most equation games forget. Addition and multiplication do not care about order: 12+34 and 34+12 are the same sum. So if your guess is the same equation with terms swapped around a + or × sign — 34+12=46 when the answer is 12+34=46 — the game counts it as solved, paints every tile green, and tells you the terms were swapped. The swap has to respect the maths: terms can only trade places around + and ×, and the worked-out value must be identical. Swapping around a − or ÷ would change the answer, so those still have to match tile for tile.
Daily, Free Play and Mini 6
Daily Equation is the main event. Everyone who plays on the same day gets the same hidden equation. Finish it and your streak grows by one. Miss a day, or run out of guesses, and the streak starts again from zero. Your best streak is saved, so there is always a record to chase. If you close the page mid-game, do not worry: your daily board is saved, and your guesses are right where you left them when you come back.
Free Play is the training ground and the time killer. Every round deals a fresh random equation from the full bank, and you can play as many rounds as you like. Free Play wins and losses count toward your played games, your win rate and your guess distribution, but they never touch your daily streak. Use Free Play to test new opening equations and sharpen your colour reading, then bring that form to the Daily.
Mini 6 is the quick round: six symbols instead of eight, like 56÷8=7, with the same six tries and the same rules. Shorter answers mean fewer digits to test, so a Mini round takes about a minute — perfect for a warm-up, or for younger players building confidence before the full game. Mini rounds share your played and won stats, and like Free Play they leave the daily streak alone.
Your full record lives in the game panel: games played, wins, win rate, current streak, best streak, and a guess distribution that shows how often you solve the equation in one, two, three, four, five or six tries. It all saves in your own browser. Nothing is uploaded, and no account is needed.
7 strategies that crack equations
- Open with a rich equation. A great first guess tests five or six different digits and two different operators at once. Something like 9×8−12=60 probes the 9, 8, 1, 2, 6 and 0 tiles and both a times and a minus in a single row.
- Pin the = sign down early. Where the = sign sits tells you how big the result is. An = sign in spot six means a two-digit answer, so the left side has to climb into double figures — and that usually means a × sign is involved.
- Never move a green tile. A green symbol is a fact. Build every later guess around it, in the same spot, and let the other symbols rotate.
- Count copies before you discard. From guess three on, answers love repeated digits. If a digit lights up once and a second copy stays gray, the answer holds exactly one copy — do not waste a third tile testing it again.
- Work backwards from the result. The right side is a number you can factor. A result like 36 begs for 9×4, 6×6 or 12×3 on the left. A result like 97 is prime, so expect a + or − shape instead of a product.
- Respect the order of operations. × and ÷ are worked out before + and −, so 2+3×4 is 14, never 20. Build your guesses with that order in mind, or the validator will refuse them for not balancing.
- Protect the streak late. On guess five or six of the Daily, play the most likely equation, not the most clever one. A plain win keeps the streak. A fancy loss ends it.
Is Daily Equation free and safe to play?
Yes. The game is free. It runs fully inside this page. It asks for no name, no email and no account. It installs nothing on your device. Your stats, your streaks and your daily board stay in your browser only.
Daily Equation is an original game made by GameOLL, built in the equation guessing genre — the style of daily maths puzzle many players know from the nerdle game. It is not affiliated with or endorsed by Nerdle. The equation bank, the validator, the daily picks and the streak system are all its own. If an equation you love is missing from the bank, tell us in the comments and we will look at adding it.

Daily Equation FAQ
Is Daily Equation free to play?
Yes. Daily Equation is 100% free. You play it right on this page in your browser. There is no download, no sign-up and no payment.
How many guesses do I get?
Six. Each guess must be a true equation of the right length, and the tiles change colour after every guess to show how close you are.
What do the tile colours mean?
Green means the symbol is in the equation and in the right spot. Yellow means the symbol is in the equation but in the wrong spot. Gray means the symbol is not in the equation at all.
What counts as a valid equation?
A valid equation has exactly one = sign, and the left side must really equal the right side. It cannot have leading zeros, double operators or a division by zero, and every division must come out whole.
Does a swapped answer count?
Yes. If your guess is the same equation with terms swapped around a + or × sign — like 34+12=46 when the answer is 12+34=46 — the game counts it as solved and paints every tile green.
What is Mini 6 mode?
Mini 6 is a shorter version of the game with six-symbol equations, like 56÷8=7. It uses the same rules and the same six tries, and it is perfect for a quick warm-up round.
When does the daily equation change?
At midnight, your local time. Everyone gets the same daily equation, and a new one arrives every day. Finish it to grow your streak, then come back tomorrow.
Final verdict: should you play Daily Equation?
Yes — if you like your daily puzzle with numbers on it. Daily Equation is free, instant and honest: no download, no account, no tricks. The validator keeps every guess fair, the swap rule keeps every win just, and one equation a day sounds tiny until the streak turns it into a ritual. Free Play and the Mini 6 are always there when one equation is not enough. Take your six guesses, and mind the order of operations.
