Casino comps (short for complimentaries) are free rewards casinos give you for playing: bonus cash, free spins and cashback online, or free meals, hotel rooms and show tickets in person. They are based on your theoretical loss, what the casino expects you to lose, not your actual results, so the more you play, the more you earn.
Casino comps are one of the few ways to claw a little value back from the house. Whether it is cashback on an online slot session or a free hotel night on the Strip, comps reward you for play you were going to do anyway. The key to getting the most out of them is understanding how casinos decide what you are worth, because once you know that, you can earn more without spending a dollar extra. This guide explains what comps are, how they are calculated, and how to maximise them.
- Comps reward play, not winning. They are based on how much you wager and for how long, not whether you win or lose.
- They are based on theoretical loss. Casinos estimate your expected loss, then return a slice of it, commonly 10% to 40%, as comps.
- Always use a card or account. Untracked play earns nothing. Online, that means joining the loyalty program; in person, the players club card.
- Never overplay for comps. A comp is always worth less than the expected loss you generate to earn it, so treat it as a rebate, not a reason to bet more.
What are casino comps?
Casino comps, short for complimentaries, are the free perks a casino gives players in exchange for their play. The term covers everything from a few dollars of online cashback to a comped suite for a high roller. The principle is identical everywhere: the casino tracks how much you wager, estimates how valuable that play is to them, and hands back a portion as rewards to keep you coming back.
Online and in person, comps look a little different. At an online casino they arrive as bonus cash, free spins, cashback and loyalty points. At a land-based casino they appear as free play, meals, hotel rooms, show tickets and, for big players, flights and limousines. Either way, comps are a marketing cost the casino happily pays because your ongoing play earns them more than the comp is worth.
How are casino comps calculated?
Comps are calculated from your theoretical loss, the amount the casino expects you to lose based on your play, not your actual wins or losses. Casinos call this your “theo” or Average Daily Theoretical (ADT), and it is the single number that decides your rewards. It is worked out like this:
Reinvestment rates vary by game, casino and player tier, but tend to land between 10% and 40% of theoretical loss (often lower on slots, higher for VIPs). This is why a common myth, that comps are a flat 10% to 15% of your total spend, is misleading: comps track your expected loss, which is only a small fraction of everything you wager. Online casinos run the same maths automatically through their loyalty program, converting every bet into points in the background.
Types of casino comps
Comps scale with your play, from small everyday perks to lavish rewards for the biggest players. Here is what you will typically find, online and in person.
How to get the most out of your casino comps
Getting more comps is not about playing more, it is about making sure every dollar you already plan to play is tracked and rewarded. These habits do exactly that:
- Always play tracked. Join the online loyalty program or pick up a players club card in person, and use it every session. Untracked play earns zero comps, even on penny slots.
- Play your normal game, never more. Comps are funded by your expected loss, so chasing a bigger reward by betting more always costs you more than it returns. Stick to your budget.
- Concentrate your play. Spreading bets across several casinos splits your value. Sticking with one program builds your tier and your rewards much faster.
- Ask for what you have earned. In person, politely ask a host or the pit boss about a meal, room or rate after some tracked play. Online, check the promotions and loyalty pages for offers you can claim.
- Say yes to offers and emails. Opt in to marketing when you sign up. Registered players get free-play coupons, reload offers and room deals you would otherwise miss.
- Redeem before points expire. Comp points usually expire after a period of inactivity, often around a year, so cash them in rather than letting them lapse.
- Know a bonus's real value. Online, weigh offers by their terms, not their headline. Our bonus calculator shows what a bonus is truly worth after wagering.
How casino comps work online
At an online casino, comps are simply the rewards built into the loyalty or VIP program, and the tracking is automatic. Every wager earns points, points unlock cashback, bonuses and perks, and your tier rises with your play, no card to swipe and no host to flag down. The same golden rule applies: the value comes from rewarding play you would do anyway, never from playing more to chase it.
