Number Equation

Guess the 8-character mathematical equation in 6 attempts.

Medium Mode

Operators: + - × ÷ (all)
  • • Up to 2 operators per equation
  • • Result always ≥ 0
  • • Division = whole numbers
  • • Example: 12*3=036

How to Play

Guess the hidden mathematical equation in 6 attempts. Each equation is 8 characters long and must be mathematically valid (the left side equals the right side).

5
Character is in the correct spot
+
Character is in the equation but wrong spot
3
Character is not in the equation

Game Rules

Basic Requirements:

  • • Equation must be exactly 8 characters long
  • • Must contain exactly one = sign (not at start or end)
  • • Left side must mathematically equal right side
  • • Right side must be a number (no operators)
  • • Use digits 0-9 and operators (varies by difficulty)
  • • Standard math operator precedence applies (× ÷ before + -)
  • • Division results must be whole numbers (no decimals)
  • • Numbers cannot have leading zeros (e.g., 01 is invalid)

Difficulty Differences

Easy Mode

Available operators: + - only

  • • Only addition (+) and subtraction (-)
  • • Exactly 1 operator per equation
