Double-ace flush

Non-standard poker hands are hands which are not recognized by official poker rules but are made by house rules. Non-standard hands usually appear in games using wild cards or bugs. Other terms for nonstandard hands are special hands or freak hands. Because the hands are defined by house rules, the composition and ranking of these hands is subject to variation. Any player participating in a game with non-standard hands should be sure to determine the exact rules of the game before play begins.

The usual hierarchy of poker hands from highest to lowest runs as follows (standard poker hands are in italics):

Some poker games are played with a deck that has been stripped of certain cards, usually low-ranking ones. For example, the Australian game of Manila uses a 32-card deck in which all cards below the rank of 7 are removed, and Mexican Stud removes the 8s, 9s, and 10s. In both of these games, a flush ranks above a full house, because having fewer cards of each suit available makes full houses more common.

"Cats" (or "tigers") and "dogs" are types of no-pair hands defined by their highest and lowest cards. The remaining three cards are kickers. Dogs and cats rank above straights and below Straight Flush houses. Usually, when cats and dogs are played, they are the only unconventional hands allowed.

Some play that dog or cat flushes beat a straight flush, under the reasoning that a plain dog or cat beats a plain straight. This makes the big cat flush the highest hand in the game.

A Kilter, also called Kelter, is a generic term for a number of different non-standard hands. Depending on house rules, a Kilter may be a Skeet, a Little Cat, a Skip Straight, or some variation of one of these hands.
