A guide to understanding casino terms: RTP, comps, staking, and more

Casino jargon can feel like a foreign language, yet a few core terms explain most of what happens at the tables and on slots. RTP (Return to Player) is the long-run percentage a game is designed to pay back, such as 96%, meaning the house edge is 4% over a very large sample. Volatility describes how that RTP is delivered: low volatility pays smaller wins more often; high volatility swings between long dry spells and occasional big hits. Bankroll is the money you set aside to play, and session budget is the portion you’re willing to risk in a single sitting.

Comps are complimentary rewards offered for play, typically tracked through a loyalty scheme. They might include free spins, meals, or room offers, and their value depends on how the venue rates your “theoretical loss” (expected loss based on RTP, stakes, and time played). Staking is simply your bet size; good staking is consistent and proportionate to bankroll, often expressed as units to avoid emotional jumps. Paylines, paylines-to-ways, and multipliers affect how wins are formed, while wagering requirements (on bonuses) tell you how much you must stake before withdrawals are allowed. If you’re comparing options, read the game rules and bonus terms carefully; even a well-known brand like duelz casino can offer promotions where the fine print matters.
