Free Spin Slots

Free spins are a staple bonus of the online world. Many casinos offer them as a single or joint bonus offer, particularly to bring in new players. However, with free spins there are usually some wagering requirements, the first and most notable of which, is the slot that they have to be used on.

This is always specific and must be adhered to by the player if they are wishing to use the bonus. Here are a few of the more commonly used slots when it comes to offering a free spin welcome bonus.


Without doubt this NetEnt slot is the most popular when it comes to winning free spins. Offered at a myriad of different casinos, Starburst is most likely used due to its simple, traditional design that yields consistent yet low wins.


Sparkling and colourful, Starburst is a five reel, ten payline slot. Whilst this may not seem like a lot, there are plenty of bonuses to keep the wins flowing nicely. Set to a purplish, space like background, the symbols are all brightly coloured gems. There are five of these gems, each with their own colour; yellow, green, orange, blue and purple, and their own value – yellow the highest and purple the lowest. Other symbols include the traditional seven and bar icons which older players will recognize from traditional old-school slots. The Starburst symbol itself is the wild.

Part of the draw for this slot is the fact that there aren’t that many symbols, which means that matching winning combinations do appear much more frequently. Blocks of symbols will also win so they don’t have to be in straight lines. For example, a triangle shape can win too. In addition, combinations can be made from right to left and left to right. With all of these extras, the simple ten paylines are negated.

Free spins

The wild Starburst symbol will appear on the central three reels only and becomes an expanding wild. By doing this it covers all symbols in that reel and offers up a free spin. This means that as well as potentially using some bonus free spins, the game will continue to offer the player more.

Twin Spin

Shiny and sleek, Twin Spin by NetEnt is set on a disco themed background complete with vibrant beams of glowing light. Twin Spin has an air of nostalgia, due in part to its use of old school icons. These include a cherry, bar, red seven, bell and a diamond. Other symbols are simply those from a pack of playing cards and include 9, 10, j, Q, K and A, all in different neon colours. A wild symbol takes the form of any of the other symbols when it lands on the reels.

A very simple slot, there are five reels but a massive 243 ways to win. These paylines only pay out from left to right though.


A couple of bonus features rounds out the excitement. The bonus is quite a straightforward one. On each spin, two of the reels will spin together and offer up the exact same matching symbols. It can occur on any of the reels, though the bigger prizes will be found if it happens on the first two reels.

For an addition to this bonus, there are times when two of the reels will actually expand to three or even up to five reels, eliciting some of the truly enormous wins. Simple, yet fun, an addictive funky soundtrack accompanies this game and when a player is already playing this for free, they really can’t go wrong.

Pyramid: Quest for Immortality

Set to a luscious deep blue background, the golden reels stand out, almost glowing. A hint of pyramid steps can be seen in the distance whilst the reels are flanked by austere looking gold statues of Ra and Anubis. NetEnt’s latest, Pyramid: Quest for Immortality is set in Egypt. Whilst the theme may not be new, the game structure and bonus features most certainly are.

A five reel slot, this game offers players 720 ways to win. With no standard paylines, a win is created when the player lands matching symbols in adjacent reels starting from the left only. A number of Egyptian themed symbols sit on the reels with the high values represented by a sphinx, the face of Cleopatra and three gods. Lower symbols are the playing card symbols 10 to Ace, all written in a style reminiscent of Egyptian hieroglyphs. The wild is a large golden ankh and this features later on in the game.

Instead of the reels spinning, the blocks holding the symbols will actually fall into place, rather like the way we imagine the pyramids to have been built. When these falling blocks create winning combinations, the blocks crumble causing more blocks to fall from above and take their place. For every three successive wins, there is a multiplier that increases by one times up to a massive ten times multiplier. During the ‘avalanche’ feature, players will notice that three of the top positions will have a purple background. If any of them make up part of a win then they become wild during the next round of play.

Free spins

With an RTP of 96.48% this is an excellent game to use with some free spins because although it may have a low variance, the wins will come regularly.

Fluffy Favourites

This Playtech produced slot is cute and cuddly. As its name suggests Fluffy Favourites is all about little stuffed toy animals. With five reels and three rows, Fluffy Favourites offers up just 25 paylines. Rather basic graphics that look like a 70s kids show are set against some cute symbol character design.

The stuffed animals comprise of a hippo, monkey, lion, panda, turtle, dragon, giraffe, duck, goldfish and a rhino. A pink elephant is the wild and scatter icon. A second scatter pops up on occasion and is in the form of claw from an arcade game.


A couple of bonus options serve to take this game up a notch. Toybox Pick is the first feature and it’s triggered by landing at least three of the claw scatters on the reels. At this point the player is able to make the equal number of prize picks as the icons that have been collected, making a maximum of five choices possible in any one game. Each prize is worth up to 100 times the total bet.

Free spins

A second feature comes in the form of free spins. These are activated by landing the pink elephant wild on the reels. Three elephants will win the player 15 spins, four awards 20 and five awards 25 free spins. At the end of the free spins round all wins made during that time will be tripled. To add to the fun, it is possible for the free spins to be re-triggered during this time simply by landing more elephant wilds on the reels.

Simple and fun

Whilst is looks graphically very simple, it more than makes up for it with its interesting game play. Rather addictive, this is a great one to get as a free spins bonus due to the number of extra bonuses on offer. To make it even more enticing, the free spins feature within the game itself is also remarkably easy to trigger providing the player with even more winning opportunities.

Aloha! Cluster Pays

The final slot most commonly used in casino free spins bonuses is NetEnt’s Aloha! Cluster Pays. Set in the Pacific Islands the reels are set on a sunny background, complete with palm trees, a Tiki mask, blue sea and a smoking volcano. The game itself has six reels with five rows and no standard paylines. As the title of the game states, wins are formed by clusters of symbols rather than lines, and nine or more symbols can be joined together to form wins.

The symbols within the game all follow the Hawaiian theme with three Tiki masks in red, blue and green, a half coconut, shell, flower and pineapple. The largest payout is the red Tiki mask, and if there are thirty of them on the reels, it is worth 10,000 times the total wager. A wild symbol is a box with a white question mark emblazoned across its front. This substitutes for the highest possible winning symbol in a specific round, though it won’t take the place of the free spins icon, which is represented by a stamp of Hawaii.


There is a number of excellently paying bonus features in Aloha! Cluster Pays. The first one is called the Sticky Win respins. This is activated completely at random after a win. All symbols that created the win will freeze in place and the reels will spin once again. Any additional symbols from the respin will simply be added to the cluster and trigger yet another spin, continuing on until no more matching symbols land on the reels.

Free spins

A second bonus comes in the form of free spins. These are activated by having at least three of the free spins scatters land on the reels. Three of the scatter icons landing will award the player with nine free spins, four scatters pays ten spins, five gives eleven and six scatters wins the player twelve free spins.

During the free spins round, the lower value symbols will be taken away (here they are the fruit and flower), leaving only the high value icons in play, meaning the wins will all be of a higher value. In addition, if the last free spin does not result in a win, then the reels keep spinning until a win finally occurs. More free spins can be won simply by having more scatter symbols land on the reels during the round.

RTP – return to player

Fun graphics, cheerful atmosphere and excellent bonuses serve to make Aloha! Cluster Pays a popular slot even without its free spins bonus usage. With an excellent RTP of 96.42%, this slot pays out wins relatively consistently. With its extra bonus feature of free spins, playing this slot with a free spins bonus awarded by the casino is an excellent way to try and get some cash prizes without paying any money in.
