  • Each sound occurs a different number of times within a loop of random length that restarts once all five sounds play simultaneously.
    This number is the sound’s frequency.
  • Three of frequencies are coprime integers in the range 2≤x≤10.
  • One of the frequencies shares a factor with exactly one of the previous three frequencies and lies in the range 4≤x≤20.
  • The fifth frequency shares factors with at least two of the other four frequencies and lies in the range 30≤x≤60.
  • Use the arrow buttons to increment/decrement the displayed frequency.
    Holding an arrow will rapidly alter the display until it is released.
  • Submit the displayed frequency by selecting a coloured button.
    If the displayed frequency matches the frequency of the sound corresponding to the colour of the selected button, the submission is accepted.
  • Correctly submit all five frequencies to solve the module.
