Day of the Dead is a unique kind of holiday celebrated specifically in Mexico. This tradition is a very important part of Mexican culture and originates in very old pre-Columbus customs respected by the Aztec and other peoples native to Mexico.

Day of the Dead consists in commemorating people that are no longer part of this world. In each family, living members remember the dead ones by putting candles near the photos or portraits, alongside with some favorite dishes of the dead.

With all that in mind, you may guess that, alongside with the images of the dead, skulls, bones, etc, the Day of the Dead themed slots are likely to feature candles, photos, and sometimes even some general Mexican things, like sombreros or guitars.

Most prominent dead people may act as scatters or wilds in these slots, while minor things like candles are likely to be low paying symbols.
