Playing an exciting slot game is a great way to relax, especially in a free spins no deposit casino. Taking advantage of no deposit bonuses gives you the opportunity to have some fun while someone else foots the bill. But to save you wasting your free spins on an obscure, dull game, here are the most entertaining slots that millions of online players find irresistible.

1. Starburst: NetEnt

Even if you’re new to slots you’ll have heard of Starburst. It’s an all time favourite because it’s colourful, easy to play and pays out at an incredibly consistent rate. The single feature activates whenever you land a wild in the three central reels. It immediately expands and sticks in place while you have the excitement of up to three re-spins. Starburst has a 96.1% RTP and wins that pay in both directions to double your chances of sparkling cash prizes. Check out where you can play Starburst with free spins.

2. Immortal Romance: Microgaming

Who doesn’t love a fast-paced vampire thriller? This atmospheric slot has proved its worth through a generous 96.86% RTP, 243 ways to win and an entertaining format. To keep your nerves tingling, all five reels can suddenly turn wild and there’s a jackpot of 12,000 times your stake. The Chamber of Spins Bonus Round has four action-packed sequences. You can sink your teeth into rolling reels, masses of free spins, exciting multipliers and expanding wilds. Play Immortal Romance at Quatro Casino and take advantage of their free spins bonus.

3. Cleopatra: IGT

You can’t fault a slot that’s achieved cult status in spite of its two-dimensional graphics. Scarab beetles, the Sphinx and lotus flowers set the scene for one of the most thrilling bonus rounds you’ll ever play. It’s known to activate more regularly than most and awards an above average number of complimentary spins. But best of all, the sequence can be reactivated time and again up to a total of 180 spins. Not bad for a 95.02% RTP! Discover now which casinos are offering free spins on Cleopatra.

4. Dead or Alive: NetEnt

Players still have a soft spot for the original Dead or Alive, a Wild West treat from 2009 that’s littered with sheriff’s badges, ten gallon Stetsons, wanted posters and cowboy boots. There’s a prairie sized 96.80% RTP and plenty of cash prizes up for grabs in this exciting slot. You’ll find twelve complimentary spins hiding out in the Bonus Round and whenever you land five matching cowboy outlaws, you receive another five spins. You’ll find it at most of our NetEnt casinos, most of which are offering free spins on sign up.

5. Thunderstruck II: Microgaming

You’d think a game from 2010 that’s based on one from 2004 would be as creaky as an old Viking boat, but players can’t get enough of this thrilling Nordic adventure. Viking gods, Odin and Thor, wade their way across the five reels where you’ll find a multi-layered Great Hall of Spins Bonus. You’ll meet Odin’s pair of jet black ravens along with multipliers worth up to six times your wager, rolling reels and up to twenty-five complimentary spins. The RTP is 96.65%.

6. Book of Dead: Play’n GO

There’s something about Rich Wilde’s treasure hunting activities in the Great Pyramid that’s captured everyone’s imagination. The amazing graphics, the 96.21% RTP and the expanding wilds based on a randomly chosen symbol all contribute to the excitement. A main attraction has to be the high volatility that creates a massive potential for winning gigantic cash prizes during the Bonus Round. You’ll receive ten additional spins that can be reactivated and the maximum win is up to 5,000 times your stake. We have some amazing Book of Dead bonuses up for grabs from some of our favourite casinos.

7. Aloha! Cluster Pays: NetEnt

The colourful, dreamy graphics of a beautiful Hawaiian paradise complete with carved stone heads make this a popular slot any day of the week. The six by five playing grid features cascading reels and an exciting re-spin that can turn up at any time and keeps on rolling until you run out of wins. The fast-paced Bonus Round has twelve additional spins that can be increased by landing more scatters. The 96.42% RTP can lead to a thrilling maximum payout of 10,000 times your stake.

8. Esquelito Explosivo II: Thunderstruck

Loud and colourful, this slot has an exuberant atmosphere through its theme based on the Day of the Dead carnival in Mexico. Chattering skulls with glittering ruby eyes or cool shades get you in a party mood as much as the addictive Mariachi band soundtrack or the multipliers worth thirty-two times your stake. But the star turn is the Bonus Round where there are fourteen complimentary spins and multipliers that increase to sixty-four times! You can play today at 777 Casino.

9. Age of Gods: Playtech

If you love nail biting suspense, this entertaining slot with its theme of Ancient Greek gods is ideal. And there’s the added attraction of a progressive jackpot that can be won at any time. While you’re waiting for it, there are masses of other cash prizes, particularly in the Bonus Round where there are nine extra spins that can be reactivated.

10. Gonzo’s Quest: NetEnt

Last but not least are the adventures of the Spanish Conquistador who behaves like a daft game show host. The graphics and the original cascading reels are absolutely awesome. Increasing multipliers worth up to fifteen times your stake and a Free Spins Bonus Round that can reactivate, make this frequently high paying slot one of the most popular ever.
