How Casino Bonuses Really Work

This guide does not promote bonuses and does not rank operators. If you are not in a state with licensed online casinos, an unlicensed site that advertises a large welcome offer is a warning sign, not a bargain.

In the states that license real-money online casinos — currently New Jersey, Pennsylvania, Michigan, West Virginia, Delaware, Connecticut, and Rhode Island — operators are subject to advertising and promotion rules. Two of the clearest written examples are New Jersey and Pennsylvania.

What U.S. regulators require operators to disclose

New Jersey's internet and mobile gaming promotion rule, N.J.A.C. 13:69O-1.12, requires the terms and conditions of each promotion to be filed with the Division of Gaming Enforcement at least five business days before the promotion is implemented. The terms must include, at a minimum: date and time limits; registration procedures; limits on who may participate; wagering requirements and limits by type of game; the order in which funds are used for wagers; eligible games; any restrictions on withdrawing funds; and rules on cancellation.

The same New Jersey rule requires promotional communications to be clear and conspicuous, in plain language. Terms must stay available for the player to review after the offer is accepted, until the promotion is finished. If a promotion uses restricted credits, the system must give a clear way to cancel, and must tell the player how much unrestricted money would be returned and how much restricted money would be removed. Once a player has met the terms, the licensee may not cap or limit winnings earned while participating in the promotion.

Pennsylvania's interactive-gaming promotion rule, 58 Pa. Code § 813a.3, requires an operator to notify the Pennsylvania Gaming Control Board and provide terms at least five days before a promotion starts. Those terms must include a description of the offer; dates and times; who is eligible; what the player must do; how to claim the offer; registration procedures; participation limits; wagering requirements and limits by game type; the order in which funds are used; eligible games; withdrawal restrictions; cancellation rules; any other information the Board requires; and a problem-gambling statement that help is available.

Other licensed states also expect promotions not to be misleading and to make material terms available. If an offer hides the wagering requirement, the expiration date, or the games that count, treat that as a reason to walk away and, if the operator is licensed, to mention it to the regulator.

Wagering requirements, in plain language

A wagering requirement (sometimes called playthrough) is the amount you must bet before you can withdraw bonus funds, and often before you can withdraw related winnings. If you receive $100 in bonus credits with a 30-times requirement, you would need to place $3,000 in qualifying wagers before those credits, or winnings tied to them, become withdrawable. That figure is an illustration of the arithmetic, not an offer.

Not every bet may count. Many offers count only certain slots or table games, or count table games at a fraction of the amount wagered. A bet that does not qualify does not reduce the requirement. Time limits are also common. If the clock runs out before you finish the playthrough, the bonus and related winnings can be voided.

The order in which funds are used matters. Some terms require you to wager your cash balance first; others spend bonus credits first. Withdrawal restrictions may lock a deposit until the bonus is completed or cancelled. New Jersey and Pennsylvania both require operators to disclose fund order, eligible games, withdrawal limits, and cancellation rules.

Hidden or easy-to-miss terms

Read the full terms, not just the banner. Look for maximum bet sizes while a bonus is active, maximum convertibles or withdrawal caps, excluded games, geographic or eligibility limits, and whether the operator can change or end the promotion. If you cannot find those terms without hunting through multiple pages, that is a problem — licensed U.S. rules emphasize that terms should be clear and accessible.

Self-excluded people, people who are underage, and people outside the licensed state are typically ineligible. A licensed operator should not market to someone on a self-exclusion list. If you are trying to cut back, a bonus email is a reason to use blocking tools and the official self-exclusion program, not a reason to reopen an account. See our responsible gambling page.

Unlicensed and offshore offers

Unlicensed sites often advertise large match offers that would not survive U.S. disclosure rules. Those offers are a frequent hook for later withdrawal delays or sudden “verification” demands after you try to cash out. If your state has not licensed online casinos, there is no state regulator to hold that site to the terms on the banner. For payment and withdrawal risks, see Payments and safety.
