The online gambling world has seen tremendous growth and evolution since the first virtual casinos opened their virtual doors in the mid-1990s. While countless new games have arrived on the scene, a select few have truly stood the test of time. These classic titles have been enjoyed by millions of players over the years and can rightfully be called the greatest online casino games of all time.
Granddaddy of Online Casino Games
Online slots have been a fixture of online platforms like Casino777 since they first began operating. The classic 3-reel slots helped the first virtual casinos attract players in the 1990s, while today’s visually stunning video slots with 3D graphics and bonus features drive much of the industry’s growth.
Slots easily account for the majority of games at today’s online casinos. Their simplicity, endless variety and potential for big jackpot payouts has made them universally appealing. Some all-time top titles include:
Starburst
This space-themed slot from NetEnt, with its exciting Starburst Wilds feature, has remained one of the most played online slots for over a decade since its 2012 debut.
Book of Dead
This Egyptian archaeological adventure-themed slot by Play’n GO provides an engaging Indiana Jones-esque experience and 92.13% RTP. It’s been a player favorite since 2016.
Mega Moolah
Microgaming’s animal-themed slot is best known for its record-setting progressive jackpot payouts, including an $21.4 million hit in 2022 that Guinness certified as the largest ever online slot jackpot.
King of Casino Table Games
No list of iconic casino games is complete without blackjack, the most popular table game both online and at land-based casinos. Its combination of skill, excitement and potential for big payouts has cemented its legendary status for over 300 years.
Today’s online blackjack games immerse players in the action with slick graphics and animations. Features like multi-hand blackjack let players enjoy multiple hands at once, while live dealer blackjack uses real-time video streams to interact with a human dealer.
The classic game remains entirely recognizable and enjoyable whether you’re playing a 3D animated game or live casino version. That consistent quality gameplay has kept fans returning year after year, allowing blackjack to maintain its perennial popularity.
Always Bet on Black and Red
The iconic spinning wheel of fortune known as roulette has an illustrious history stretching back hundreds of years. Today it’s the second most played balloonies slot game online after slots. Players keep coming back to bet on black, red and their favorite numbers in hopes of hitting it big.
While the game has evolved from the original French roulette wheel to add variants like American and European roulette, the fundamentals remain the same. The online versions add slick visuals and gameplay for a polished experience with all the excitement of a real casino.
Players appreciate how online roulette allows them to set their own pace of play, take time to consider strategy and even try popular betting systems like the Martingale Strategy from the comfort of home.
Playing with Perfect Strategy Pays Off
Video poker emerged in the 1970s but didn’t find widespread popularity until the first online casinos began dealing virtual hands in the 90s. Since then, it has become a player favorite that combines familiar poker gameplay with the thrill and pacing of slots.
The goal is to form a strong five-card poker hand that outranks the computer dealer. Getting a winning hand triggers an instant payout without having to wait for other players to act. Top variations like Jacks or Better, Deuces Wild and Bonus Poker remain perennial favorites today.
While incorporating an element of chance like slots, video poker also involves skill in deciding which cards to hold or discard. Using optimal strategy can lower the house edge dramatically, making video poker potentially one of the most profitable casino games you can play if you learn the proper play for each variation.
