However, the main reason we think Gonzo’s Quest is one of the best games is that it has some of the best graphics of any slots out there across any slot site. The animation and graphics really aid the narrative of the game and every one of your spins helps the story of this loveable hero move along that extra bit more. What a game.

Perhaps the best slot with this theme, Dragon’s Luck combines some great attention to detail with great graphics and bonus features, meaning that each and every one of your spins feels different.

Why we love this slot

We are big fans of slots that make the most of a classic theme, while still delivering something new and Red Tiger Gaming has certainly done this with Dragon’s Luck. The Ancient Chinese or Chinese culture theme is done very often but rarely done as well as this, especially when you combine your spins on this title with our first deposit bonus for new players. Slots do not come much more visually engaging than this one, as from the moment you start wagering through to your bonus spins, everything is wonderfully designed and detailed.

Whereas some games require you to get a few good spins in order to trigger bonus features, the random bonus features in this one are something to enjoy as well. It means that you never really know when your bonus spins are going to come and there are not too many slots that hand out bonus spins in this way. So, if this sounds like the kind of game you want to spend the bonus funds from your deposit on, give some spins to Dragon’s Luck and see if bonus spins come back your way. A popular title in the world of mobile casino, we are confident that it will not take you long to realise why so many enjoy wagering their bets on Dragon’s Luck with a minimum bet of 20p and a max bet of £500. As always, when wagering options go this high, we do encourage players to use their spins wisely and please gamble responsibly.

Jungle Jim and the Lost Sphinx

Another popular theme for online slot games is the Ancient Egyptian theme and many of the best slots across casinos use the likes of pyramids, pharaohs and hieroglyphics as symbols on the reels and symbols to line up with your spins. Jungle Jim and the Lost Sphinx blurs the line between slots with this theme and slots with a more adventurous theme, as you follow Jungle Jim on his mission to explore ancient tombs in search of the Lost Sphinx.

As ever, this is a title you can use your bonus funds on thanks to a first deposit bonus at Slotzo, so be sure to make the most of the match bonus that will help you double your money before wagering your bet. Deposit £20 and you will be able to use £40 for wagering your spins on Jungle Jim and the Lost Sphinx. These terms apply for all new customers, with bonus spins also available for selected games.

Also, there are four bonus features on offer with extra bonus spins being one of them. Look out for a multiplier feature that will grow with each of your spins, too, as the amount you started out wagering, could quickly multiply into some bonus funds. Consecutive wins means bigger multipliers, with Jungle Jim and the Lost Sphinx offering a level system that goes as follows: Level 0 is played on a 5×4 reel set with 35 pay lines, Level 1 sees a multiplier increase to 2x, Level 2 sees a multiplier increase to 3x, Level 3 sees the multiplier increase to 4x and you play on a 5×5 reel set with 50 pay lines, Level 4 gives a multiplier increase to 5x, and finally, Level 5 offers a multiplier increase to 10x.

What makes this Slot so Special?

Once again there are many reasons why we like this casino offering but the main reason is perhaps the original theme it has. Ancient Egyptian slot machines are great but a little bit too common, whereas the mixture of this theme with one that brings so much adventure makes for a really unique title in Jungle Jim and the Lost Sphinx. Finding that pesky sphinx provides the main narrative of this one, while hoping for productive spins and smart wagering should be your main goal. Again, if you decide to play this slot machine using money from your first deposit, deposit £20 and have £40 for your wagering needs.

She offers 5 reels and 20 pay lines to work with, and those who have the Welcome Bonus valid will be pleased to hear that your bonus funds can be gambled in this title.

IGT has an appreciation for the classic slots of old and there is certainly a retro charm to Cleopatra, with the 5 reels making for a simple enough title to play while feeling somewhat modern as well.

The modern side of the slot machine comes from the bonus rounds and IGT tends to get this right more often than not.
