How to play

  1. Use all five dice exactly once, in any order, with +, −, × or ÷.
  2. The host chooses Left to right or PEMDAS (× and ÷ first, then + and −; equal precedence goes left to right). No parentheses or exponents. Fractions and negative steps are allowed.
  3. Got a solution? Press “I Can Math!”, then enter your full calculation privately in 15 seconds.
  4. A wrong answer or timeout means you sit out this round. Everyone else keeps the same dice.
  5. The round starts at 1 point and grows by one each minute of active solving. Claims pause the clock. Optional shared hints reveal one equation piece each active minute; scoring stays the same.
  6. First to 11 or more wins. Between rounds, take your time. The next dealer rolls when you’re ready.
  7. Tap a die, then an operator, and repeat. Undo removes your last entry. Keyboard: numbers select dice, + − * / choose operators, Backspace undoes, and Enter submits. Your draft stays private; submitted answers are shared.
  8. Use hint copies the shared hint into an empty answer. All incorrect submitted equations appear when the round ends; timeouts have no equation.
LEFT TO RIGHT EXAMPLE2 + 3 × 4 − 5 + 6 = 21

5 → 20 → 15 → 21. With PEMDAS, this expression equals 15.
