In the game of poker, a kill game is a game played using a variation of fixed limit betting rules. A kill game provides for the play of kill hands, which involve an extra blind bet and increased betting limits. Kill games are infrequent but not uncommon in home poker games; many casinos offering poker will introduce the kill to a table on request or during certain scheduled times. Kills are most often used in community card poker variants like Texas hold 'em, which normally use blinds as the primary forced bet, and this article assumes such a game is being played, but the concept can be made to work with almost any poker variant with only minor changes to suit the betting protocol of the game. Kill games serve to mitigate wins by dumb luck or flukes. They also serve to mitigate bad beats, which are wins by a player who made questionable choices from an odds standpoint. While such players are often inexperienced, they may win a substantial hand despite making poor decisions such as raising or calling on a drawing hand with very low probability to make the hand, which can be frustrating to more experienced players. Such poor decisions are likely to eventually or gradually result in a large loss; kill hands make this loss happen sooner rather than later if the player persists in loose aggressive play. Thus, kill hands encourage a more disciplined, tighter betting style less likely to call/raise and more likely to fold. However, as the kill hands are only played infrequently, the general betting style of the table is looser than if the kill stakes were normal limits. Kill games among a table of more experienced players also create a heightened thrill of risk; a player is on a winning streak, or a big pot has just been won, and the next pot is likely to be bigger. Kill games can in such cases encourage looser play as well.

Comps

In the context of casinos, comps are complimentary items given out by casinos to encourage players to gamble. The amount of comps that a player is given usually depends on what game they are playing, how much they are betting, and how long they have played. Most casinos have hosts who are responsible for giving out free items and contacting players to bring them back to the casino. Pit bosses can also award comps at table games. Most casinos now require a player to have a player's club or similar card, so that their play can be tracked and comps awarded.

The lowest level of comp available at most casinos is free alcohol and other beverages. Many casinos provide free drinks to anyone who is gambling.

The second level of comp that many players earn is free meals. Many casinos have several restaurants and may require more play to earn a comp to the higher end restaurant. Often the player is given a certain amount to spend, but sometimes, particularly with high rollers, the player may be given the right to order as much food as they want.

The next level of comps is usually free hotel rooms. Many casinos have attached hotels, but those that don't may have the ability to comp rooms to a hotel nearby. Many casino hotels have higher quality rooms, such as suites, villas, presidential suites and so on for bigger bettors. Many players who receive hotel rooms receive a package called RFB for room, food, and beverage or RF for smaller bettors, or jurisdictions where casinos are not allowed to give free alcohol.

Many casinos also offer other comps, especially to high rollers. These may include airfare reimbursement, limo rides, prostitution services, tickets to shows, golf, free concierge services, cash back, private gaming areas, and private jet service.

Casinos also frequently offer players comps by mail. These may be free bet offers, free meals, discounted or free rooms, or entries into tournaments or prize drawings.
