The 67 Number Game

The 67 Number Game is a daily math puzzle where your goal is to make the four given numbers equal 67.

Each puzzle gives you four numbers and a set of allowed operators. Your task is to build a valid expression that hits the target exactly.

You must use every number exactly once.

You can combine the numbers with standard operators like:

• +
• -
• ×
• ÷
• ( )

Some puzzles also allow special operations:

• ! factorial can only be applied directly to one of the original raw numbers.
• ^ power requires the exponent to be one of the original raw numbers.

That means some expressions are valid, while others are not, even if the math works out.

The challenge is finding a legal expression that reaches 67 using the tools available.

A new puzzle appears every day at midnight UTC.

Why we like it:

• ✅A satisfying mix of arithmetic, experimentation, and logic.
• ✅Special rules around factorials and powers make it extra interesting.
• ✅Quick to try, but often surprisingly tricky to solve.

Hint: Start by testing whether one number works well as a factorial or exponent, since those usually create the biggest jumps.
