Our Picks for the Right Slot Game
It’s not just about the theme — the best slots to play online also depend on your background, budget, and playing style. Here are some quick tips from Legalcasino experts, tailored to different player profiles:
Start with classic 3-reel machines. They’re easy to understand and don’t have too many features.
Low-volatility games pay more often. You lose slower and play longer. Choose slots with low minimum bets — ideally around £0.10 per spin.
Try video slots with bonus games and special features. These are more complex but offer more variety.
Pick high-volatility games that can pay big. You won’t win often, but the prizes can be huge.
Choose slots with an RTP of 96% or higher. These tend to return more of your wagers over time.

Top 10 Slots Themes
Have a look at the slot styles UK players enjoy most. Each group includes hundreds of titles, and some sites like Unibet even let you filter by visuals or storylines. Right now, we've highlighted one of the best slot machines to play for each theme.
Egypt
Ancient Egypt-themed slots often feature pyramids, scarabs, pharaohs, and gods like Ra or Anubis. These games create a mysterious, treasure-hunting atmosphere and usually include expanding symbols or hidden chambers. The theme sticks around thanks to its timeless draw of ancient legends.
Example: Eye Of Horus – Reel Time Gaming
Fruit
Classic fruit machines remain a favourite with their simple icons: cherries, lemons, bells, and 7s. Modern fruit-themed slots add cluster pays, multipliers, or Megaways while keeping the visual simplicity. Their fast gameplay and easy-to-understand mechanics make them appealing to both new and nostalgic players.
Example: Super Fire 7s – Inspired
Adventure
These games take players through temples, jungles, or ancient ruins, often with a character leading the way. They usually focus on dynamic gameplay and cascading reels. The theme appeals to those who enjoy a sense of journey and discovery.
Example: Gonzo’s Quest – NetEnt
Asian
Expect golden dragons, glowing lanterns, koi ponds, and temple rooftops. Backgrounds often feature cherry blossoms or mountain views. Music can be calm and meditative or loud and celebratory. Common symbols include lucky coins, scrolls, and fortune frogs. Many enjoy the mix of tradition, elegance, and symbols of luck.
Example: 5 Lions Dance – Pragmatic Play
Magic
Light effects, runes, and glowing symbols set the tone. Some designs use spellbooks and wizards. Others feature magical girls or fantasy creatures. Visuals are friendly and smooth, which keeps the mood relaxed.
Example: Moon Princess 100 – Play’n GO
Mythical
Temples, storms, and glowing skies are common visual elements. Soundtracks are dramatic, with slow builds and sharp cues. Symbols often show divine powers, ancient weapons, or magical beasts. Some titles include random features triggered by gods. Often chosen for its clear style and connections to well-known myths.
Example: Rise of Olympus – Play'n GO
Ocean
Themes include fishing trips, sea creatures, and underwater scenes. Visuals show waves, bubbles, and cartoon-style gear. Sounds are calm, with splashes or soft music. Characters are often fishermen or friendly animals. The light tone and steady rhythm make it easy to follow.
Example: Fishin' Frenzy Big Catch – Blue Print
Wild West
Set in dusty towns or rugged plains, Wild West slots showcase cowboys, gunslingers, saloons, and bounty posters. Colours lean warm, with lots of brown, red, and gold. Music comes with twangy guitars, sharp whistles, and tense pauses. The outlaw style resonates with fans of high-risk, high-reward gameplay.
Example: Wanted Dead or a Wild – Hacksaw Gaming
Cosmic
Planets, stars, and glowing orbs appear across dark skies. Visuals often use deep blues, purples, and flashes of neon. Symbols may include meteors, galaxies, or energy fields. Soundtracks are slow, with electronic tones and echoes. Fits well when you're in the mood for something quiet and hypnotic.
Example: Cosmic Moon – Games Global
Horror
Distorted minds, locked rooms, and flashes of violence create a tense setting. Visuals are gritty, with harsh lighting and unsettling details. Sounds are sharp, looping, or deliberately off. Not far off from a horror film—just with spins instead of scenes. Good choice when happy-looking games get boring.
Example: Mental II – Nolimit City
