Jackpot comma is the difference between a stack of 7 29/16 and 6 2/1 (alternatively, between a stack of 7 32/29 and an octave). Equal divisions that are not multiples of 7 cannot temper it out.

Temperaments

Tempering it out produces the jackpot temperament, which sets 29th harmonic (octave-reduced) to be represented by 6\7.
