How to Win Big at the Casino

Although most casino games are random, scoring big casino wins can be made easier by learning some key skills. Here are some of the most important things to consider when trying to win big at casino sites:

Learn About House Edge & RTP

Remember, the real money online casino always possesses the house edge in every game you play. The house edge is the average profit that the casino will expect to earn on every wager. Conversely, the return to player (RTP) rate of a game is the average amount of a wager that a player can expect to win back.

Both of these numbers are calculated over thousands of spins or games and are a useful way to determine the likelihood of scoring big casino wins. But remember, the biggest casino big wins are often scored on games with higher house edges, such as slots, rather than on low house edge games, like blackjack or video poker.

The house edge in online slots for real money ranges between 2-15%, on average. So, when looking at return to player rates, or percentages, the slots you want to play to improve your chances of winning would boast a RTP of 97-98%.

The house edge in online blackjack for real money is less than 1%, which means more winnings for the player in the short-term.

The house edge in video poker is also less than 1%, which is rare to find in most online casino games.

Practice Bankroll Management

The best way to win big at the casino is to practice sound and patient casino bankroll management. Don’t go chasing losses or you’ll end up in so deep a financial hole, you’ll never recover. Nobody wants to experience that feeling. Always be aware of your financial situation and seek help if you feel you may have a gambling addiction.

Remember what you learned about house edge above, some games pay the player 97-98% of the time, which means it is possible to make money gambling. However, in the spirit of bankroll management, you also need to know when to say when and walk away from a session with some profits in hand.

Study Your Craft

You wouldn’t start a household project without doing your research and learning the essential skills. The same should go for risking real money on casino games. Study up on how to play blackjack, online poker, and online craps if you want to improve your chances of casino big wins.

Embrace Bonuses

Keeping your wallet flush with cash, credits and free spins casino bonuses is a helpful way to win big at the casino. In an effort to earn your business, online casino operators promote four-to-five figure welcome bonuses to new players in hopes that you create a new account and make a first deposit. What better way for you to win a big casino bonus than to turn your $3,000 deposit into $6,000 via a 100% match welcome bonus.

Casino Big Wins History

Tales of big wins at the casino are similar to those who share stories of finally making a hole-in-one on the golf course. If there isn’t a witness or witnesses, the details get a little fuzzy. Even with internet investigative reports and eyeballs everywhere, details are a little sketchy on the biggest casino wins of all-time, but names like Archie Karas and Kerry Packer pop up on every list after they won $10’s-of-millions in a single night playing a variety of games.

Then there is the story of a gambler from Los Angeles who risked $100 on Excalibur Casino’s Megabucks slot machine and walked away with nearly a $40-million jackpot.

When it comes to online casino big wins, look towards the progressive online slot machines with the name “mega” in the game’s title. Absolutely Mad Mega Moolah paid out more than $23.6-million, Mega Moolah $23.5-million and Mega Fortune $21-million.

Biggest Casino Wins of All Time

With the availability of legal online gambling options in the US and around the world, it’s little wonder that so many big casino wins are now achieved online. Here are some of the biggest jackpots ever achieved by players at a big win casino:

Position Big Win Casino Payout Win Big Casino Game Country of Win Year of Win
1 $24 Million Mega Millions Slot Finland 🇫🇮 2013

3 $23.5 Million Mega Moolah Unknown 2018
4 $17.2 Million Mega Moolah UK 🇬🇧 2015
5 $16.7 Million Mega Moolah Unknown 2020

Big Win Casino Bonuses

Range of Banking Options

We highly recommend you check out the casino deposit page before creating an account. You want to find a casino that accepts a range of deposit and withdrawal methods, particularly Bitcoin. Most casinos will accept Visa, Mastercard, and other popular banking methods, but this is not universal.

For big casino wins, you should also check the casino’s policy on withdrawals. Some casinos will only pay out large amounts in small instalments over a longer period of time.

Range of Games

Be sure to look at the casino’s selection of games. For the biggest casino wins, you’ll want to look at their selection of slots, particularly progressive jackpots such as hot drop jackpots.

If you want to win big at casino sites, you will probably not be as focused on table games or live casino games. That being said, these games are incredibly fun and can provide variety to your online gambling experience.

Bonus Offers & Promotions

Most casinos will proudly promote their promotions, but always be sure to read the bonus terms and conditions to learn what you need to do to be able to withdraw your potential winnings.

Casino License & Security

If you’re searching on Google for how to win big at the casino, chances are that you’ve come across some sketchy sites guaranteeing massive wins. Unfortunately, scams do exist so we always encourage our readers to exercise their best judgement when choosing a big win casino.

Check to see if the casino is licensed and, if it is, where it is licensed. The most reputable licensing authorities in the world include the Malta Gaming Authority and Curaçao eGaming.

Furthermore, check to see if the casino utilizes encryption and firewall software to protect player personal and financial data. These are factors that Gamble Online’s expert consider when reviewing sites. So if casino has our recommendation, it is a safe gambling site.
