About Equation Guess
Equation Guess works like a word guessing game, but with sums. The answer is a true equation eight characters long, such as 12+35=47. Every guess you enter must be a true equation as well, and each character is marked as right, misplaced or absent.
How to play Equation Guess
- Type an equation eight characters long, like 12+35=47, and press Enter. Every guess must be true.
- Use the digits 0–9, + − × ÷ and one =. × and ÷ are worked out before + and −.
- Each character is marked: ✓ right character in the right spot, ↔ in the equation but in another spot, or not in it at all.
- You have six tries. Fewest guesses wins, then the fastest time.
Tips & strategy
- Open with an equation that uses many different digits and two operators, such as 9×8−7=65.
- Find where the equals sign goes early on; it fixes how many digits the result has.
- Remember that × and ÷ are worked out before + and −.
- Digits can repeat, but no number may start with a 0.
- Use your second guess to test digits you have not tried yet, even if it cannot be the answer.
Equation Guess: questions and answers
Which symbols can I use?
The digits 0 to 9, the operators + − × ÷ and exactly one equals sign.
Why was my guess not accepted?
Every guess must be a true equation of exactly eight characters, with a single whole number after the equals sign and no leading zeros.
How is Equation Guess ranked?
Fewest guesses first, then the fastest time.
Is the order of operations used?
Yes. Multiplication and division are worked out before addition and subtraction, from left to right, so 2+3×4 makes 14.
Can the answer be negative or a fraction?
No. The result after the equals sign is always a whole number of zero or more, and every division must come out exactly.
