Slot machines are some of the most popular games in casinos. Instant millionaires can be created through an incredible range of bonus features available on land-based slots…or you can just sit back, enjoy the fun bright colors and walk off with a couple of extra dollars.
According to the University of Nevada, in 2017 there are 166,860 slot machines and other electronic gaming devices in Las Vegas alone. Obviously, the most popular slots are the ones with bonus games, so let’s check out some of the best bonus games out there on the casino floor.
What better way to begin this list than with one of the most iconic slot machines of all-time. The Egyptian-themed Cleopatra is a 5-reel, 30-payline title that is slots gaming at its purest. Players can trigger a free spins bonus round where 15 free spins are up for grabs with a 3x multiplier. It’s one of the more simplistic bonus features around but the payouts make it worthwhile. There is a reason this is not only a fan favorite but has spawned a sequel game and seen the series thrive as online slots.
Zeus (WMS Gaming)
Next up on this list is another classic from the casino floor. The Greek mythology-themed Zeus is an institution in its own right. It is a 5-reel, 30-payline slot machine where players can win up to 100 free spins as a bonus. The potential wins from those free spins have helped propel the slot into slots immortality. Follow-up releases of Zeus II (available on social platforms only), Zeus III, and Zeus: God of Thunder have been equally well received by slots players.
Chests of Plenty (Ash Gaming)
Everybody loves a good old pirate-themed slot machine. Luckily, there is the 5-reel, 20-payline Chests of Plenty that can give players their pirate fix. Undoubtedly, the best part of this slot is when players can use a treasure map to hunt down the treasure in a bid to win up to 2,000x their stake. Another bonus feature also allows players to match gems in treasure chests to win prizes.
Beverly Hillbillies (IGT)
The Beverly Hillbillies was a smash hit US television sitcom that ran between 1962 and 1971. It revolved around a family of hillbillies who move to the luxurious Beverly Hills area after striking it rich by finding oil on their land. The series is the inspiration for this 5-reel, 25-payline slot machine. The Millionaire Mile bonus feature is one of the most exciting on a slot ever released. Players must spin the ticker to navigate around the trail and try to win as much cash as possible. It is a game within a game.
The Walking Dead (Aristocrat)
The Walking Dead is a hugely popular US TV show that has been shown on AMC since October 2010. It follows a group of survivors during a zombie apocalypse. Slots developer Aristocrat decided to grab the licensing deal quickly and have produced this thoroughly enjoyable 6-reel slot machine release. Players can play either using the Center for Disease Control wheel or the Atlanta wheel. This gives the game extra depth. The allure of a $500,000 potential jackpot also sets it apart from the rest of the crowd.
Elvis the King (IGT)
Elvis has become synonymous with Las Vegas over the years so the gambling industry has always sought to take advantage of that special relationship. A fine example of that is this 5-reel, 25-payline slot based on the legendary singer. Elvis the King has a little bit of everything. The music blaring out will really get Elvis fans on their feet. Free spins can be won. Players can receive either a broken heart or a fantastic prize at the Heartbreak Hotel. Wild reels can also randomly appear on the reels during the base game.
Book of Ra (Novomatic)
Is it too much to have two Egyptian-themed slots on this list? Well, not when the second title is of the caliber of the 5-reel, 9-payline Book of Ra slot machine. This game has proved particularly popular on the European continent with Novomatic really pushing it in a number of countries in that region. The free spins can be re-triggered and this can result in some of the most thrilling bonus game action players could possibly imagine.
Rainbow Riches (Barcrest)
The 5-reel, 20-payline Rainbow Riches slot machine is one of those games that comes along every once in a while and captures the imagination of the slots playing public. Initially, players were critical that the game did not offer a free spins bonus round. However, when it soon became obvious how incredible the Pots of Gold Bonus, Road to Riches Bonus, and Wishing Well Bonus were it was clear the free spins mattered not. It is no surprise that this game spawned several sequels online including Rainbow Riches: Reels of Gold and Rainbow Riches: Pick ‘n’ Mix.
