Dream Vegas and other top UK online casinos have lots of games themed around mythology, and Zeus’s Thunderbolt is one of our top picks. With 30 paylines and a maximum bet of £5 per line, you could be in for a seriously huge win.

Land five of the Zeus icons and you’ll win 2,500x your stake, plus the game comes with wilds, and a respins feature.

Starburst doesn’t come with any complex gameplay or bonus rounds, and the simplicity means that it’s the ideal game for newer online casino players, so you could look to use any free spins on it.

Book of Dead

There are loads of “Book of” slot games that you can play at top UK casinos like Casimba, but Book of Dead by Play’n Go is among the best of them.

Set in an ancient Egyptian tomb, you’ll be going on a journey with explorer Rich Wilde, and when you play you’ll need to look out for the special book symbol which acts as the scatter and awards you the free spins round! There are also expanding symbols to increase your chance of a win, plus Book of Dead comes with 10 paylines and an RTP of 96.21%, so it’s an excellent game to try.

Eye of Horus

Eye of Horus is one of many Ancient Egyptian themed games that you can play at 21 Casino. Created by Reel Time Gaming (a smaller studio), Eye of Horus is themed around the mythical Egyptian god, and the slot comes with a whole lot of special features like symbol upgrades, a bonus round of 12 free spin that can be re-triggered, and the chance to win an impressive fixed jackpot of 10,000x your stake!

You don’t have to be a fisherman to love the Big Bass Bonanza game (available at Karamba Casino) and its whole line of spin offs. The game comes with an above average RTP of 96.71%, and high volatility, and of course the impressive graphics and gameplay that you can always expect from Pragmatic Play titles.
