After extensive research conducted by our Top 10 team, we uncovered the most popular online slot themes among British players that can lead to some extraordinary real money winning opportunities on both desktop and mobile devices.

  • Ancient Rome

    1. Ancient Rome

    There isn't any better imagery than gladiators battling it out in a colosseum. Ancient Rome-themed slots capitalise on this and are very popular with the UK audience. With new releases coming out all the time, a lot of them have unique bonuses while giving you the option to play across multiple pay lines.

    • Gladiator - The theme of this slot is based on the Gladiator movie. Characters from the movie compromise the symbols, with Lucilla and Commodus being the highest-paying. You also have Gracchus and Proximo, who are medium payouts. The image of the colosseum is the Scatter, and there are two prominent features, the Gladiator Bonus and the Colosseum Bonus
    • Caesar's Empire - Caesar's Empire's background consists of the Roman Colosseum, and it does a great job of encompassing the Ancient Rome theme. You will be able to trigger 10 free games if you land the Coliseum scatter, which is on reel 5. This can be combined with one or more Caesar symbols. When you do trigger a free spin, the sky will darken and turn to night, which makes for an exciting visual experience.
  • Egyptian

    2. Egyptian

    Another common theme would be Egypt. Cleopatra can be found everywhere in the slot world, but mostly you'll see her in Egyptian Cobra and Night in Cleo. When playing Egyptian-themed slots, you can expect to see numerous symbols, including King Tut, hidden treasures and pyramids. Some of the top Egyptian-themed slots also come equipped with free spins bonuses to further enhance your online gaming experience on both desktop and mobile devices.

    • Egyptian Cobra - Egyptian Cobra has a Mega Jackpot, which is the image of King Tutankhamun. The mask is also prominent in other slot games including Pharaoh Gold.
