Verified launch rule

Calculator Module solver

After you enter the game's arithmetic result and its lamp lights, choose the result parity and lamp color to get the final digit.

Entered result parity

Choose the result parity and the lamp color. Unsupported or incomplete inputs never produce an answer.

How the Calculator Module rule works

  1. Calculate and enter the result shown in the game.
  2. Wait until the lamp lights, then identify whether your result is even or odd.
  3. Choose the lit lamp color. The solver returns the verified final digit.

The calculation and lookup stay in your browser. The site does not send the parity, lamp color, or answer to analytics.

Calculator Module lamp rule table

Use this lookup only after entering the arithmetic result in the game and seeing the lamp light. Each cell is the final button to press, not the arithmetic result.

Which result is odd or even?

Use the arithmetic result you entered, not the final digit from this table. A whole number ending in 0, 2, 4, 6 or 8 is even; one ending in 1, 3, 5, 7 or 9 is odd.

What if the lamp has not lit up?

Do not guess a color or use a table answer yet. Enter the arithmetic result in the game first and wait for the lamp. This tool performs the second-stage lookup; it does not evaluate the game's arithmetic expression.

Practice the parity-and-lamp lookup without a live timer, or choose a different module solver.
