You might have heard the idiom "canary in the coal mine." If not, there's an interesting and somewhat dark story behind it, which is best explained in the Dead Canary slot. In the late 19th and early 20th century, canaries were used by miners in the coal mines to detect the presence of carbon monoxide.
Due to the bird’s small size and rapid breathing, the canary would quickly succumb to the presence of poisonous gas, giving miners ample time to escape or take necessary measures. Sad, right? But not in the case of the Dead Canary slot, where you root for as many canaries dying (imaginary ones, of course) to come near to the grand prize of a staggering 65,000x the stake.
