Daily Equation
How to Play
Game Instructions
- Guess the hidden equation in 6 tries.
- Each guess must be a valid 7-character equation (e.g.,
10+20=30). - Equations use only numbers and basic operators (+, -, ×, ÷, =).
- Calculations are performed left to right (no order of operations).
- Use logic and math skills to narrow down possibilities.
Why Play Daily Equation?
Research shows that mathematical puzzles engage the brain's dorsolateral prefrontal cortex, which is responsible for working memory and executive function. Unlike standard arithmetic drills, Daily Equation requires "deductive reasoning"—you must simultaneously calculate values while testing logical constraints (e.g., "if the 5 is orange, it cannot be in the second slot").
This dual-processing strengthens neural pathways associated with problem-solving and pattern recognition. Regular practice can improve mental math speed and reduce "math anxiety" by turning calculation into a game of logic.
Tips for Success
- Start with simple equations using common numbers and operators.
- Pay close attention to color clues after each guess.
- Green tiles mean correct character and position; orange means correct character, wrong position; gray means not in the solution.
- Try to eliminate impossible numbers/operators with each guess.
- Use the process of elimination and pattern recognition.
Advanced Strategy Guide
The "Opener" Strategy
Your first guess is critical. A strong opening equation like 12+34=46 or 9*8-7=65 uses unique digits
and
tests specific operators. Avoid repeating numbers (e.g., 20+20=40) in your first
guess,
as it reduces the amount of information you gain.
Commutative Law
Remember that 1+2=3 and
2+1=3 are different
answers in
this game. If you know an addition or multiplication is involved, but the
positions
are orange, try swapping the order of the numbers.
Isolate the Operator
Try to determine the operator early. If you know there is a * (multiplication), the
resulting number will likely be larger, restricting your possible digits for the
equals sign.
Origins of the Game
While the "Wordle" format became famous in 2021 as a word game, the concept of guessing a hidden code using feedback dates back to the 1970s game "Mastermind" (and arguably earlier to the paper-and-pencil game "Bulls and Cows"). Daily Equation adapts this classic logic mechanic to mathematics. Instead of guessing a sequence of colored pegs or letters, players must construct a mathematically valid statement.
Example Puzzles
- Easy:
12+23=35(Addition) - Medium:
34×02=68(Multiplication) - Hard:
123-45=78(Subtraction) - Expert:
96÷12=08(Division)
Color Clues Explained
-
5Correct: The number or operator is in the solution and in the correct spot.
-
+Present: The number or operator is in the solution but in the wrong spot.
-
1Absent: The number or operator is not in the solution at all.
