High rollers do not usually arrive at a casino carrying a suitcase of cash. They arrive with a marker: a line of credit issued by the casino itself, drawn in chips at the table and repaid after the trip. A marker is, in legal terms, a cheque. You sign it, the casino gives you chips, and the casino deposits the marker against your bank account after a set period, usually 30 days. It is the standard way serious players fund their play, and it is also the most misunderstood tool in the casino.

Applying for a marker starts before you travel. The casino's credit department will ask for a bank reference, details of your accounts, and a credit application authorising them to verify your funds. They check that the money exists and that your history supports the amount you are requesting. First-time applicants should allow at least a week, and sometimes two, because the checks are done by hand and the casino will not rush a credit decision for a player it does not know.

The credit limit depends on your verified funds and your history with the casino. A player with a strong banking record and previous trips may be approved for a limit in the hundreds of thousands or more, while a first-timer will start smaller. The limit is not a target: it is the maximum the casino will let you draw, and drawing the full amount on a first visit is a fast way to be noticed for the wrong reasons.

Using a marker at the table is simple. You sign a marker for the amount you want, the pit gives you chips, and the marker is held by the casino. You can sign further markers up to your limit during the trip, and you can repay markers in cash or chips before they are deposited. Many players settle their markers at the cage before leaving, which avoids the bank deposit entirely and keeps the arrangement clean.

Repayment is where markers demand respect. In Nevada, an unpaid marker is a criminal matter, not just a civil debt, and the casino will pursue it. The standard deposit period is 30 days, though some casinos allow longer by agreement. If you cannot repay, talk to the casino before the deadline: extensions are sometimes granted, silence is not. A player who communicates and pays on a plan keeps their standing; a player who disappears loses it permanently.

Markers also change how the casino treats you. A player with a marker is a known quantity, and the host team will track your play, your average bet, and your theoretical loss, because that is how comps are calculated. The credit line itself does not earn comps; the play funded by it does. A $100,000 marker that sits unused earns nothing. A $50,000 marker played steadily at the tables earns rooms, dining, and host attention in proportion to the theoretical loss it generates.

There are alternatives worth knowing. Front money is cash you deposit with the casino in advance and draw against, which carries no debt and no repayment deadline. Some players prefer it precisely because there is nothing to repay. Wire transfers on arrival are another option, though they are slower and less convenient at the table. Markers are the most flexible tool, but they are the only one that creates a legal obligation, so they demand the most discipline.

The mistakes to avoid are consistent. Never sign a marker for more than you can repay from funds you already hold. Never use a marker to chase losses after a bad session, because the credit makes it easy to keep playing past the point where you should have stopped. Never ignore a marker after the trip, and never assume the casino will forget it. Casinos have entire departments for exactly this, and they do not forget.

A marker is a professional tool for a professional approach to the casino. Set the limit with your host before the trip, decide your loss limit in advance, settle at the cage before you leave, and keep the credit line smaller than your comfort zone rather than larger. Used that way, it is the safest and most convenient way to play at high stakes.

Q: Is a casino marker a loan? A: In practice, yes. It is a short-term, interest-free line of credit secured by your bank account, and in Nevada an unpaid marker is treated as a bad cheque.

Q: How long do I have to repay a marker? A: Usually 30 days, after which the casino deposits it against your bank account. Some casinos grant extensions if you ask before the deadline.

Q: Does having a marker earn me comps? A: Not by itself. Comps are earned by the play the marker funds, measured by your average bet, time played, and the game's house edge.
