Free slots explained
Free slots allow you to play the latest and most popular online slot games without having to wager real money bets. In other words, you can experience all the excitement and features top-rated slots offer at no cost to your wallet whatsoever.
The trade-off is that you can’t win cash payouts and jackpots when playing free slots, but that doesn’t mean it’s a waste of time. With free slots, you can try out games as and when you want to get a feel for what you like and which titles you most enjoy.
It’s worth noting that free slots are not the same as free spins bonuses, which give you a specified number of spins on slots free of charge from which you can win real money.
What free slots games can you play?
Online casinos offer an incredible range of free slots for players to choose from. Here are the most common slot types available to try for free:
Video slots use colourful and immersive video graphics to display the reels. They normally come with a multitude of special features and in-game bonuses, such as wilds, multipliers, free spins, upgraded symbols and mini-games. Most video slots have five or more reels with at least 10 to 20 paylines.
Classic slots closely resemble mechanical fruit machines and often have just three reels with five paylines or fewer. They are fairly limited in terms of additional features (if they have any at all), making them perfect if you prefer simple and traditional slots action in which all the focus is on the base game.
Megaways slots massively boost the number of paylines with a six-reel layout on which two to seven symbols can appear on every reel. Most Megaways titles offer up to 117,649 ways to win on every spin, although some games have an upper limit of over 500,000.
Progressive slots feature jackpots that increase in real-time whenever a player bets on the game. These games can involve some of the biggest prizes you’ll find on offer at online casinos, such as Mega Moolah’s Mega Jackpot, which starts at £1 million. However, you can’t win the jackpot when playing progressive slots in free mode.
As the name indicates, penny slots allow you to place bets from just one penny per spin. That makes them a popular option when taking advantage of bonuses at minimum deposit casinos.
There are thousands of free slots that you can play where and when you like on mobile. These are available at both casino mobile sites and apps that you can download from your app store. All the free slots featured on this page are also mobile-friendly.

Free slots betting strategies
Slots are games of chance, but there are a few things to try when playing free slots that may help if you decide to start gambling for real money.
Firstly, try playing free slots with a return to player (RTP) percentage above the 96% average for online slots. These games are expected to pay out more money to players, so when you switch to real money mode, you can take advantage of more favourable odds.
You should also bear in mind the game’s volatility. If the slot has low volatility, monitor how big its payouts are, while if the volatility is medium to high, play it for free to see how many spins it takes on average to win. This information can be handy when deciding if it’s worth staking actual cash on a game.
Lastly, when playing free slots, ensure your time spent on the reels gives you a good idea of how any in-game features or bonus rounds work, so you know exactly what to expect when real money is on the line.
