Classic Slots

We kick things off with classic slots games. With their 3 reels and one payline classic slots are the simplest type of slot game so they are a perfect choice if you're a total beginner.

Lots of classic slots hark back to the early days of one arm bandits and fruit machines so you will find plenty of classic slots games with the traditional Fruit, Bell and BAR type symbols you are probably familiar with, however classic slots can have any theme.

Classic slots tend not to have bonus games and many classic slots do not feature special symbols such as Wilds and Scatters which does keep play simple but with the possible downside that they may be less exciting than more advanced and feature rich slots. That said if you're a complete newbie, a very simple, no thrills classic slot game can be a great way to start playing.

Despite the fact they have been overshadowed by video slots in recent years, slots game developers do continue to release classic slots for both desktop and mobile play and they remain a popular option for slots players. If you'd like to play a classic slot game right now then give our very own Classic slot game a spin!

Bonus Slots

Bonus slots are any game that features a bonus symbol. What the bonus symbol does varies from game to game but typically in a video slot it will, when it makes up part of a winning payline, trigger a special feature or bonus round.

Bonus slots are certainly one of the most popular types of slots as bonus games and special features help keep play interesting and can reward the players with more opportunities to win,

Bonus features vary from game to game so you might find that after a bonus is triggered symbols shuffle position on the reels, multipliers are awarded, free spins are triggered etc. Often, especially in the more advanced video slots games, you will be taken to a new screen to play a bonus round. These bonus games come in many different guises including the most common pick-an-item type game (eg you are presented with 4 mystery parcels and you must choose which one to open to reveal a prize).

Check out our very own exclusive bonus slots - we've got numerous bonus slots games to play, many of them with brilliant bonus rounds that are totally unique and exclusive to Free Slots 4U!

3D slots

With their amazing animated graphics, the latest 3D slots games are some of the most visually attractive slots games around. In terms of actual gameplay, 3D slots don't tend to be any different to 2D video slots, the only real difference being the enhanced graphics and animations that 3D slots developers such as BetSoft use to make their slots games look incredible!

3D slots obviously take inspiration from the likes of animated cartoons and video games and in terms of themes you'll find a huge selection of fun "stories" and characters to choose from including Fantasy, Horror and Science Fiction type games.

We've got a small selection of games with 3D slots features here including our Fast Slots game which features fighter jets zooming out of the screen!

I-slots or Interactive Slots were first introduced by slots developer Rival. The unique thing about these popular slots is that they are based around a story such as a murder mystery or romance and as you play the game you will be given options to choose which path to take next, like an interactive adventure. I-Slots provide an entertaining twist on the standard slots game as each time you play you can discover new things.

Here at Free Slots 4U we've got our very own exclusive I-slot style game called Superior Slots, which is themed around the story of a Mafia boss and your role in his organisation!

Progressive Slots

Progressive slots are slots games that have jackpots which increase every time someone makes a wager. Jackpots can rise into multi-million dollar prize amounts as players around the world wager on a game and add to the prize pool.

Some games have random progressive jackpots which means absolutely any player can take the entire pot, at anytime, while other games have specific requirements to trigger a progressive jackpot win such as hitting 5 of the same symbol while betting the maximum amount as possible.

We have our very own selection of free to play progressive slots game right here at Free Slots 4U and while we can't promise the multi-million-pound jackpots of the big casinos, we do give away a $20 cash prize at random to anyone who manages to win one of our progressive jackpots.

Penny Slots

With a penny not worth very much, slots game manufacturers and developers have designed penny slots games to help you part with your spare change! These games cost 1 penny to spin but watch out because if you're betting on more than one payline then those pennies can soon add up.

Tip: Penny slots with their minimal wager requirements are a good way to test out a slot game when you're ready to step up from free play mode.

For an example of a penny slot you can try out our very own penny slot game.


'Pokies' is the slang name Australians use for slots and fruit machines (the term itself is believed to derive from "Poker Machine".) They were first legalised in 1956 in New South Wales following the arrival of the first Pokie game called Clubman. Pokies are now found all across Australia in Casinos, bars & clubs etc. Despite the different name, the games are exactly the same as the slots games you will find elsewhere. Pokies are incredibly popular in Australia with both the online and mobile pokies markets expanding at a phenomenal pace.

High Roller Slots

Do you have money burning a hole in your pocket? Feeling flush after a win? Then High Roller slots games might be just the thing! When you're ready to up the stakes, High Roller slots let you make the biggest wagers for the chance to reap the biggest rewards. Be warned, however, High Roller games are not for everyone - while High Rollers do tend to pay out a bit more than normal limits slots games, which you can use that to advantage, and can provide you with a "buzz" of several impressive wins in a short space of time, you must keep an eye on your funds as it might only take a few losing spins to see you wiped out!

Multi Payline Slots

A multi-payline slot game (also know as a multi-line slot) is simply any slot game with more than one payline. The average amount of paylines in a slot game is probably around the 15 - 25 payline mark, however, you can find games with many more paylines.

When you gamble on more than one payline, you increase the possibility of getting a winning line but your bets cost more, of course.

Here at Free Slots 4U most of our games are multipayline games, ranging from 3 up to 30 paylines, and our Slots by Paylines page is handy if you want to find a slot with a specific number of paylines.

Multi-reel Slots

Multi-reel slots are not actually that common and (many online casinos do not actually have any at all) but the principle is easy enough to understand: instead of spinning one game's set of reels you spin multiple game's reels at once, just as if you were playing three, four, five or more slots games at once so if you've ever thought "I wish I could play 9 slots games at once but I've only got one pair of hands" then a multi-reel slot is the answer to your prayers!

No one here amongst the Free Slots 4U is a big fan of Multi-reel slots to be honest - we prefer to spin one set of reels at a time and the scarcer nature of the Multi-reel slots games means there are fewer games to choose from.
