How to Play 37, The Math Puzzle

37 is a free daily math puzzle. You roll seven dice and combine them using addition, subtraction, multiplication, division, parentheses and exponents so that your equation equals exactly 37. It is designed to be quick to learn and genuinely hard to master — smart games for smart people.

The core loop

You are given seven dice.
Build one equation from them that evaluates to the target: 37.
Each die is its own value — you can’t push two dice together to make a bigger number (a 3 and a 7 do not become 37).
Standard order of operations applies (parentheses, exponents, then multiply/divide, then add/subtract).

Game modes

Easy — Practice Mode

Learn the moves. All white dice, no pressure, unlimited rounds. Untimed, new dice whenever you’re ready, and no power-dice rules — just reach 37.

Challenge — Power Dice Mode

Same goal, with colored power dice. Practice the rules, untimed, with unlimited rounds. Use two of the three power dice correctly for a valid solve.

Daily Challenge

One puzzle, one shot. Everyone gets the same seven dice each day, refreshed at midnight ET. Beat the clock in one sitting — leave before finishing and it counts as a forfeit. Climb the global leaderboard, keep your daily streak alive, and land a Perfect solve (all three power dice used correctly) to earn a Puzzle Piece.

The power-dice system

In Challenge and Daily modes, three of your dice are colored power dice:

Green — add or subtract with it (+ or −).
Blue — multiply or divide with it (× or ÷).
Red — use it as a base or a power (^).

Use at least 2 of the 3 correctly for a Valid Solve.
Use all 3 correctly for a Perfect Solve & earn a Puzzle Piece 🧩

Winning examples

Every example below is a real solution that equals 37 (each one is verified against the game’s equation engine, so none can drift to a wrong answer).

Easy

Plain and simple — ×, +, −: 6*6+1+1-1-1+1

Nested parentheses + division: ((6*3)+4+5)+5*4/2

An exponent — 2⁵: 2^5+1+1+1+1+1

Challenge

Two parenthesis groups (Valid): (6+1)*5+(6-4)+1-1

Two of three power dice (Valid): 6*6+6-2-1-1-1

Exponent power — 6² (Perfect): 6^2+3*1+1-2-1

Parenthetical exponent — (6−1)² (Perfect): (6-1)^2+6*2+1-1

Daily Challenge

Two parenthesis groups (Valid): (5+1)*6+(4-3)+1-1

Two of three power dice (Valid): 5*6+6+3+1-1-2

Exponent + a parenthesis (Perfect): 6^2+(6-5)*1+1-1

The (3÷3)=1 trick (Perfect): 6^2+(3/3)*1+1-1
