Aztec Treasure

This popular 5-reel slot game takes you into the heart of the ancient Aztec world, as you hunt for hidden treasures beyond your wildest imagination. The game is a 20-payline progressive slot which offers up to 20 free spins every time you hit three or more "Aztec idol" icons on the reels. The respectable 95% RTP might not be the best offering in the world, but with jackpots reaching up to 5000 times your original bet, there isn't much to complain about. 

Cash Bandits

Any fan of the Grand Theft Auto game series will enjoy Cash Bandits, which is quickly gaining a reputation as one of the most entertaining and innovative online slot machines in the game right now. Fittingly, a bank vault serves as the wild symbol in this game and hitting a full line of these bad boys will net you 2500 coins. There's also a handy autoplay option which allows you to let the reels spin continuously so that you can maximize your gaming efficiency. 

Builder Beaver

This cute forest-themed slot puts the player in the seat of Builder Beaver, a plucky little creature who is on a mission to build the greatest dam of all time. The protagonist may be cute, but the jackpot prizes here are nothing to smirk at. Even those betting with just one coin can win up to 10,000 coins should they get five beaver symbols in one go. Even if you only manage to get three, the game will reward you with 12 free games. 

Ceasar's Empire 

History fans will prefer this thoughtfully-created Roman-themed slot, in which you follow the ill-fated emperor Ceasar in his quest to enrich his vast kingdom. The Ceasar wild card is the one you want to get in this game, as even getting just one of them in a line will triple your current jackpot. This game first attracted attention due to the fact that most casinos offer 100 free spins on this one for first-timers, meaning you can play for free to get a feel for the smooth gameplay and sharp graphics.

Pig Winner 

Unsurprisingly, given that it is now currently the Chinese Year of the Pig, the newly-released slot title Pig Winner has proved a massive hit with gamers around the world. This latest release from Realtime Gaming is a three-reel video slot which offers a whopping 243 different ways to win the top prize. The maximum payout is set at 200 times the original bet on a spin which, although lower than some other slots, offers players a higher chance of hitting the jackpot. 

Sevens and Stripes 

If you prefer a dash of good-old-fashioned American patriotism with your gaming, then Sevens and Stripes offers all of the red, white, and blue action you could hope for. The Founding Fathers theme means that the marching drums and flutes in the background music might get a little irritating, but this old-school 3-reel game is still an absolute classic. It's a progressive jackpot game which allows players to multiply their potentials winnings significantly by betting slightly more. Its totally respectable Return-to-Player (RTP) of about 97% also helps sweeten the deal. 

Nova 7s

Sci-fi fans will appreciate the razor-sharp graphics and riveting narrative of this space-age slot thriller. Nova 7s is set on a barren asteroid hurtling through space, occupied by a hardened space cadet who must navigate the treacherous extraterrestrial terrain whilst scooping up big jackpots. There are a total of four different wild mechanics you can hit; 'solar flare', 'nova', 'super nova', and 'hypernova', all of which offer increasingly lucrative jackpots, as well as hundreds of free spins. 

High Fashion

This hyper-stylised slot game is ideal for female players and fashion-forward gamers in general. The action takes you through the runways of Paris, New York, London, and Milan as you navigate the world of high fashion and spin your way to riches. There are two wilds, the male model icon and the female model icon, both of which can double your current jackpot if you get more than three at a time. Another coveted symbol to play for is the runway symbol, which will give a payout worth 1000x your original bet if you manage to get five in a row.
