What is Detective Equation?
Detective Equation is a deduction game where you must guess a hidden 8-character mathematical equation. Each guess must be a valid equation using digits (0–9) and operators (+, −, ×, ÷, =). After each guess, colored feedback reveals which characters are correct, misplaced, or absent. The detective theme frames this as code-breaking. You have limited attempts to deduce the exact equation based on partial information.
How it works
You enter an 8-character equation that is mathematically valid (e.g., 12+34=46). After submitting, each character is color-coded: green means correct position, yellow means the character exists but is misplaced, and gray means the character is not in the equation. You have six attempts to find the exact equation. The challenge lies in balancing mathematical validity with deductive reasoning.
Rules
- Each guess must be a valid 8-character equation
- Use digits 0–9 and operators + − × ÷ =
- Green indicates correct character and position
- Yellow indicates correct character but wrong position
- Gray indicates the character is not in the equation
- Solve within six attempts
Tips & Strategies
- Start with equations that use a variety of digits and operators
- Pay close attention to the position of the equals sign
- Use process of elimination for digits that appear gray
- Remember that the equation must be mathematically true
- Consider common equation patterns (e.g., a+b=c, a×b=c)
- Double-check your math before submitting
Why players enjoy Detective Equation
Equation puzzles combine the satisfaction of word-guessing games with arithmetic reasoning. The format is familiar to anyone who has played Wordle-style games, but the numeric twist adds a layer of mathematical thinking. Each puzzle is quick — typically solvable in a few minutes — and provides a clear sense of progress as you narrow down possibilities.
Daily mode
Detective Daily includes equation-style challenges as part of its rotating format. If you enjoy numeric deduction, the Daily case offers a fresh equation to crack every day.
