Casino bonuses come with their own set of terms that are often unfamiliar, inconsistently explained, or misunderstood. Most issues players run into with bonuses are not caused by the bonuses themselves, but by confusion around the language used to describe how they work.
This glossary explains the key casino bonus terms players actually encounter, focusing on mechanics rather than specific bonus types. It covers the language used in bonus rules, wagering conditions, balances, and withdrawals, without duplicating the bonus type explanations found elsewhere.
Use this page as a reference when reading casino bonus offers or bonus code details. Understanding these terms makes it much easier to judge whether a bonus is worth using, how it affects withdrawals, and how bonus codes and casino bonuses fit together in practice.
Casino Bonuses – Key Terms
Bonus Balance – The portion of your account balance that comes from bonus funds and any winnings generated while a bonus is active. Money in the bonus balance is usually locked until wagering requirements are met. For example, if you deposit $50 and receive a $50 bonus, winnings earned while the bonus is active typically sit in the bonus balance until conditions are cleared.
Cash Balance – Your real-money funds and any winnings that are free of bonus conditions. Cash balance funds are normally withdrawable at any time, subject only to standard verification checks. Once a bonus is cleared or forfeited, eligible winnings usually move from the bonus balance into the cash balance.
Bonus Code – A promotional identifier used to activate a specific casino bonus or promotion. The code itself has no monetary value and does not affect game outcomes or withdrawal processing. Bonus codes simply tell the casino which bonus terms to apply to an account.
Bonus Terms and Conditions – The rules that govern how a casino bonus works. These typically include wagering requirements, eligible games, maximum bet limits, cashout caps, and time limits. Withdrawal restrictions always come from these terms, not from the bonus code used.
Wagering Requirements (Rollover) – The amount you must wager before bonus-related winnings become withdrawable. This is usually expressed as a multiple, such as 30x the bonus or 30x the bonus plus deposit. Higher wagering requirements increase the risk of losing the balance before withdrawal.
Contribution Rate – The percentage of each wager that counts toward meeting wagering requirements. Slots often contribute 100%, while table games may contribute partially or not at all. A game with a 10% contribution means only $10 of a $100 bet counts toward wagering.
Maximum Bet Limit – The highest amount you are allowed to stake per spin or hand while a bonus is active. Exceeding this limit can result in bonus winnings being voided. Maximum bet limits matter more with large bonuses, where balances appear high but betting freedom is still restricted.
Maximum Cashout Limit – A cap on how much you can withdraw from winnings generated using a bonus. Even if you win more, any amount above the limit may be removed. These limits are set by bonus terms, not by bonus codes.
Auto-Applied Bonus – A bonus that is applied automatically by the casino without requiring a bonus code or manual selection. Auto-applied bonuses are common for welcome offers and are triggered based on factors like location or referral source.
Bonus Forfeiture – The act of cancelling a bonus and removing bonus funds and related winnings from an account. Players often forfeit bonuses to make remaining cash balance funds withdrawable when wagering requirements are not worth completing.
Eligible Games – The games that can be played while a bonus is active and that contribute toward wagering requirements. Some games may be restricted entirely, while others may contribute at a reduced rate.
Bonus Abuse – A term used by casinos to describe misuse of promotions, such as claiming the same bonus multiple times, creating duplicate accounts, or intentionally violating bonus rules. Bonus abuse can result in bonuses being removed or winnings being voided.
Playthrough – Another term for wagering requirements, referring to the process of wagering the required amount before withdrawals are allowed. For example, a $1,000 playthrough means $1,000 must be wagered before cashing out.
Sticky Bonus – A bonus where the bonus funds themselves cannot be withdrawn, only the winnings generated from them. Sticky bonuses are often used in no-deposit promotions and usually come with withdrawal caps.
Non-Sticky Bonus – A bonus where both the bonus funds and any winnings may become withdrawable once wagering requirements are met. These bonuses generally offer more flexibility than sticky bonuses.
Verification (KYC) – The process of confirming a player’s identity and payment details before withdrawals are processed. Verification is required regardless of whether a bonus or bonus code was used and is separate from bonus rules.
Time Limit (Bonus Expiry Period) – The amount of time a player has to meet wagering requirements after claiming a bonus. If the time limit expires before wagering is completed, the bonus and any related winnings are usually removed. Time limits vary widely and are often overlooked until a bonus is forfeited automatically.
Opt-In Bonus – A bonus that requires the player to actively select or accept it before it is applied. Opt-in bonuses can appear in account dashboards or promotion menus and may require confirmation even if no bonus code is used.
Bonus Lock – A state where funds cannot be withdrawn because a bonus is active. A bonus lock remains in place until wagering requirements are met or the bonus is forfeited. This lock applies to bonus-related winnings, not to verified cash balances.
Game Exclusion – A restriction that prevents certain games from being played while a bonus is active or excludes them from contributing to wagering requirements. Game exclusions are often listed in bonus terms and can affect progress toward withdrawal.
Promotion Eligibility – The criteria that determine whether a player can claim a bonus, such as being a new customer, using a specific currency, or registering from an eligible region. Eligibility rules apply independently of bonus codes and are enforced automatically.
Withdrawal Adjustment – A recalculation of account balance that occurs when bonus conditions are violated or a bonus is forfeited. During an adjustment, bonus funds and related winnings may be removed while eligible cash balance remains.
Casino bonuses are easier to navigate once the terminology is clear. Most issues players encounter come from misunderstandings around wagering rules, balances, limits, and eligibility rather than from the bonuses or bonus codes themselves. Knowing how these terms fit together makes it easier to assess offers, understand withdrawal conditions, and avoid common mistakes. When the language is clear, bonus codes and casino bonuses become simpler tools rather than sources of confusion.
