What Does -3 Mean in Betting?

When playing online casinos, there are a few key terms and phrases you need to know. These three words will appear time and time again during your gaming experience, so familiarizing yourself with them will make it much easier to have an enjoyable time doing what you love most.


This is the process of randomly matching two or more numbers or symbols together to form a winning combination. For instance, say you are playing a slot game and a five-card monte game simultaneously. In the case of a winning combination in both games, you would receive your prize money from both games combined. In the case of a single-game winner, you would collect the winnings for that game.

The object of the game is to match a series of numbers or symbols together in a row to create the winning combination. The numbers or symbols do not need to be consecutive, and in many cases it is preferable if they are not. Think of a slot game where you are trying to match three or more symbols of the same kind (i.e. coins, scatters, etc.) to win.


This is the process of placing multiple bets on the same event, with the hope of winning big. For example, if you are playing at a sportsbook and the betting line for the next big game is at -3, you might want to parlay all your favorite teams to make the bet. You are essentially spreading the risk of losing money over a series of wagers.

The strategy behind parlaying is simple; you are hoping that one of your bets will come through, and if it does you win your money plus what you earned from the previous bet. So if you are playing with real money, parlaying is a viable option as long as you are confident that one of your bets will pay off. However, if you are playing for fun, it might not be the wisest choice.


This is the opposite of parlaying, as it pertains to single-game betting. When you lay a bet, you are making a wager on the outcome of a single event. For example, in a hockey game, you might lay a bet on the score of the game. If the bet loses, you lose your money (unless the NHL bookies are offering a nice sign-up bonus at the moment).

Unlike parlaying, where you are trying to secure multiple wins with a single bet, you are looking to win a single bet in the case of a lay. This might be a good choice for those who are looking to win a quick and easy amount of money. However, like with parlaying, laying a bet on a single event means you are assuming the risk of losing money if the bet does not come through. Also, like parlaying, betting on a single event is not advised if you are playing for fun.


This option is available to online casino players who are interested in taking some of the risk out of their gambling experience. Say you are playing at a land-based casino and happen to meet the right person. You can exchange some private information for an insurance policy that would cover your gambling losses. The premiums will be deducted from your winning and the benefits will be paid out to you if you meet the right conditions.

Even though you are playing for fun and not risking any serious money, you might consider insurance as a way to cut your losses in case you meet the right person or if you play a very unlucky combination of numbers or cards. In the case of a land-based casino, this is a very popular option as you can walk away knowing you have some security in the form of insurance. Plus, you can always contact the casino staff if you are having trouble with the gambling, and they will be able to help you.
