With prizes such as 75,000, 125,000 and 250,000 coins up for grabs for matching either.
Cleopatra(IGT)
What better way to begin this list than with one of the most iconic slot machines of all-time? The Egyptian-themed Cleopatra slot is a 5-reel, 20-payline title that is hugely popular for a reason.
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.
Zeus (WMSGaming)
Next up on this list is another classic from the casino floor. The Greek mythology-themed Zeus slot is an institution in its own right. It is a 5-reel, 30-payline game where players can win up to 100 free spins as a bonus.
Thepotential wins from those free spins have helped propel the slot into slotsimmortality. Follow-up releases of Zeus II, Zeus III, and Zeus: God of Thunderhave been equally well received by slots players.
Buffalo (Aristocrat)
The legendary Buffalo slot from Aristocrat is a superbly volatile game with 1,024 paylines. The result? You can win money really quickly and those wins are easy to come by, but your bank balance can also plummet quickly too.
The bonusround at this game is where you can really make your money. You get free spins,which might sound standard, however they have a twist. You can land a megamultiplier of up to 27x!
If you’relucky enough to get the multiplier, you’re in for a huge payday.
BeverlyHillbillies (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, 20-payline slot machine by IGT.
TheMillionaire Mile bonus feature is one of the most exciting on a slot everreleased. Players must spin the ticker to navigate around the trail and try towin as much cash as possible. It’s a game within a game!
TheWalking Dead (Aristocrat)
TheWalking Dead is a hugely popular US TV show that has been shownon AMC since October 2010. It follows a group of survivors during a zombieapocalypse.
Slots developer Aristocrat decided to grab the licensing deal quickly and have produced this thoroughly enjoyable 6-reel slot machine release.
Playerscan play either using the Center for Disease Control wheel or the Atlanta wheel,which gives the game extra depth. You also have the chance to win free gamesand a mega $500,000 jackpot.
Elvis theKing (IGT)
Elvis hasbecome synonymous with Las Vegas over the years, so the gambling industry hasalways sought to take advantage of that special relationship. A fine example ofthat is this 5-reel, 25-payline slot based on the legendary singer.
Elvis theKing has a little bit of everything. Here’s one player enjoying the Hound DogBonus, Jailhouse Rock Bonus and Jukebox Bonus:
The musicblaring out will really get Elvis fans on their feet. If that doesn’t, the freespins sure will!
Book ofRa (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, 10-payline Book of Ra slot machine.
This gamehas proved particularly popular on the European continent with Novomatic reallypushing it in a number of countries in that region.
Thejackpot is great on this game, though with just 10 paylines you will need torely on Lady Luck to help you win. The bonus round is packed with expandingsymbols, which is ideal for bringing in extra wins.
RainbowRiches (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 toRiches Bonus, and Wishing Well Bonus were, it was clear the lack of free spins didn’tmatter. And the jackpot is insane!
It is no surprise that this game spawned several sequels online including Rainbow Riches: Reels of Gold and Rainbow Riches: Pick ‘n’ Mix.
Try Before You Buy
If you want to get a feel for any of these games before you play them at the casino, we suggest playing the slots for free first.
This way you can get a sense of their volatility, how they work and whether you think it’s worth your while before you put down any money on online slots.

Everi’s Mata Hari Slot Review
The original Mata Hari, officially known as Margaretha Geertruida MacLeod (nee Zelle) was a Dutch dancer and courtesan. Having once studied to be a kindergarten teacher, the German spy and femme fatale worked as a circus horse writer, artist’s model and an exotic dancer.
Mata Hari was a well-known seductress and would use this to her advantage by seducing influential men for intelligence. She was ultimately exposed to the French as a German spy, was tried for espionage and executed by a firing squad. It’s said that she blew a kiss to the firing squad after refusing to be tied to the stake.
Everi pays homage to the captivating enchantress in this five-reel slot game featuring the “man-eater” Mata Hari.
Mata Hari: Core Gameplay
The Mata Hari slot machine features five reels, four rows, and 40 paylines. Players can bet a minimum of $.50 up to a maximum of $1,000 per spin.
The Mata Hari symbol is the highest paying symbol within the game and can appear on the reels in purple during the base game or green, during the bonus round. The Mata Hari symbol reigns supreme during free spins where her symbol becomes wild—and her seductive dancing proves it so!
Other valuable symbols in the game are three intriguing male figures—who clearly have some sort of designs on the seductive lady.
Regular wild symbols are easy to spot with the word “wild” clearly shown. The wild symbols will substitute all other symbols to complete winning combinations, except for the “Free Spins” symbol.
The Mata Hari slot machine is equipped with all of the standard functions including an auto-spin button. When clicked, you’ll be provided with the option of 10, 20, 50, 100 or 200 spins. You can quit the auto-spin feature at anytime by pressing the stop button.

The Game’s Good Looks
During her heyday, Mata Hari gained fame as an exotic dancer in the glittering city of Paris. Her act was inspired by the artistic rage of her day for Orientalism.
On stage, the seductress dressed in sexy garb inspired by the harem girls of the Far East. The soundtrack features exotic sounds that reflect Mata Hari’s stage performances.
Everi is making a name for itself based on its brightly colored games. This one is no exception.
Bonus Round: Free Spins
Mata Hari’s depicted beauty aside, the most enticing feature of this slot game are the free spins. Indeed, these spins brim with lucrative potential.
To trigger the the free spins bonus round, you will need to collect 3, 4 or 5 free spin symbols across anyone of the five reels.
- 3 Free Spin Symbols: 2 x multiplier and 10 free spins
- 4 Free Spin Symbols: 3x multiplier and 15 free spins
- 5 Free Spin Symbols: 10x multiplier and 20 free spins
The bonus round includes a nudge feature. If the Mata Hari slot symbol appears on any one of the five reels, the symbol turns into a wild and will fill the entire reel to complete winning combinations. Three or more Mata Hari symbols can equate to fairly substantial wins.
Our Final Thoughts
Everi has infused the notion of the femme fatale into this game’s design through creative artwork and subtle animations.
The Mata Hari slot combines elements of traditional slot games with a few of the modern touches that Everi has become known for.
Slot Machine Reel Strips
The game lacks the complex bonus rounds available from other software houses. The free spins feature is the main attraction to the game but is quite difficult to hit. If you do manage to win those free spins, the potential for a substantial win increases significantly.
