Why play free slots?
When you play slots for free, you get to try out the latest releases from the world’s leading providers with no risk whatsoever. You won’t find that luxury at land-based casinos.
Free online slots also give you a feel for the real thing, as the graphics, gameplay and bonus features are identical to those in the real money version. It’s a great way to test the waters before you make a casino deposit and play for real cash.
At OnlineCasino.ie, our free games collection is constantly growing, with new titles added on a regular basis. You can use our Arcade library above to search for your favourite slot or if you’re not sure what you’re looking for, there are handy filters to browse by software developer, most popular, newest and alphabetically.
Types of free slot games
There are thousands of online slots to choose from at the best casinos. Here are some of the common free demo slots variants you’ll find at Irish online casinos:
Online video slots replicate the hi-tech machines you’ll find in land-based casinos. They use computerised random number generators (RNGs) and smooth HD graphics. Video slots also offer a range of payline options and lots of bonus features.
Classic online slots offer simple gameplay with minimal paylines and bonus features. They often resemble traditional fruit machines in terms of symbols, themes and bonuses.
Experience big-name Vegas slots online without leaving Ireland. You can try free online video slots adapted from land-based titles by developers like IGT and Bally.
Progressive online slots offer special jackpots contributed to by millions of players across the network. You could win a large multi-million-euro jackpot if you’re lucky enough to trigger the jackpot on offer!
These are slots that only cost €0.01 per spin, making them a cheap option if you decide to play for real money.
Some online casinos offer free spins bonuses, typically as part of a welcome package. To claim these, you usually need to sign up to the casino, after which you’re awarded with a set number of free spins to use on specific slot games. A free spins no deposit bonus means you don’t need to deposit any funds to qualify.
You can play thousands of free mobile slots on your iPhone or Android. Mobile slots are available to play through downloadable casino apps or your smartphone browser. The look may be different, but the same great gameplay applies.
Megaways slots offer lots of ways to win on a single spin. Popular titles like Treasure Box Kingdom, Gonzo’s Quest Megaways and Temple Tumble Megaways offer up to hundreds of thousands of paylines. Rather than landing symbols in traditional paylines, you can match symbols anywhere on adjacent reels.
Free slots by theme
Developers love coming back to tried-and-tested themes when making free slots you can play for fun. Here are some of the most popular themes among Irish punters:
The best free slot games with an Irish theme boast leaping leprechauns, pots of gold and lots of jackpot action. Check out free slots like Barcrest’s Rainbow Riches with its lucrative trail bonus.
Ancient Egyptian-themed free online slots offer more riches than a Pharaoh could hope for. Check out the range of Egypt-inspired free slots, such as Cleopatra by IGT.
Asian-themed slots like SHFL Entertainment’s 88 Fortunes and Playtech’s Jin Fu Long celebrate the Chinese themes of New Year and good luck. You can also bag a progressive jackpot in many of these slots.
The best movie-themed free demo slots boast themed bonus features and even incorporate clips from iconic films and TV shows. Some of our favourites include Microgaming’s Game of Thrones and Jurassic Park.
Slot games covering myths and legends are timeless. Whether its stories of Greek, Roman or Viking gods or King Arthur and the Round Table, we can’t get enough of these legendary tales being transformed into thrilling slot games. Check out Pragmatic Play’s Gates of Olympus or Playtech’s Age of the Gods series.

Our top tips for playing free slots online
Here are some top tips for playing free slots games:
Check the RTP
This tells you how much a slot game pays out on average over time. The average slot RTP is 96%, which means you’re expected to win €96 for every €100 you wager. The higher the RTP, the better.
Research bonus features
Modern slots typically have an array of exciting and potentially lucrative in-game bonuses, from free spins rounds to multipliers. Learning how to unlock these features is very important if you’re planning on playing slots for real money.
Study the paytable
The paytable displays all the essential information about a slot game, including the available symbols and potential payouts, available bonus features, and so on. It’s always a good idea to study this before playing a slot for free or real money.
Gamble responsibly
Remember, slots are ultimately games of chance, so there’s no way to guarantee a win. Don’t get into the habit of chasing losses even when playing free slots, as this is a bad gambling practice to follow.
