A glossary of casino terms: from ‘comp’ to ‘variance’

Understanding casino jargon helps you read game rules, compare offers, and manage risk with clear expectations. This glossary covers common terms you will hear on the floor and in online play. A “comp” is a complimentary perk, such as meals or rooms, typically tied to your theoretical loss. “House edge” is the built-in statistical advantage of the venue over time. “RTP” (return to player) is the long-run percentage a game pays back, while “bankroll” is the money you set aside for play and never exceed.

Several terms relate to how games behave in practice. “Variance” (or volatility) describes how widely results swing: low variance tends to deliver smaller, steadier wins; high variance produces longer losing stretches punctuated by bigger payouts. “Hit frequency” is how often a game pays anything at all, which is not the same as profitability. “Payline” and “paytable” explain how slot combinations award prizes. “Wagering requirements” set how much you must stake before withdrawing a bonus. “Table minimum” is the smallest bet allowed, and “shoe” refers to the device holding multiple decks in blackjack.

Industry educators often translate these concepts for mainstream audiences. A well-known example is gambling mathematician Michael Shackleford, whose analyses helped popularise terms like expected value, advantage play, and variance among everyday players; his primary profile is GamblingMath.
