A blaze is considered in poker to be a hand in a non-standard game of poker which has 5 face cards that ranks above a flush. This term applies to all poker games played in land based casinos and the gaming houses online. It can also be defined as a hand that holds an array of cards with five faces without a corresponding sequence in arrangement. The cards don't usually have a ranking order in cardroom poker but this may be different in privately played poker games.
Lowball poker players often use the term "blaze" to add lustre and color to their tough luck stories. Meanwhile the literal meaning of a blaze which is a hand that holds an entire stretch of face cards is more common than all other meanings. For the popular type of blaze, it consists of a 5-face card that ranks between 2 or 3 pairs of the same type. Under various poker rules, a blaze may be seen as a complete hand.
