Top 11 Free Slot Apps – The best slot games to play

Top 11 Free Slot Apps – The best slot games to play on your smartphone

Free slot apps are a great way to practice for real money UK casino online because they allow you to learn more about game mechanics before you start your gambling journey.

While these free games might not be as thrilling as a regular casino, they sure have a great vibe, and they’re a great time killer, especially if you enjoy slot machines.

Bear in mind that all the free slot games mentioned in our article are intended for 18+ adult audiences. Thus, under the UKGC verification rules, the apps will run an age check before allowing you to try out any of these games. Additionally, success with these slot apps does not imply success with real casinos, so you should use these games solely for entertainment.

How we select free slot app

After analyzing hundreds of free slot apps from both the App Store and Google Play, we’ve compiled a list of the top casino games to play on mobile. Here are the key factors we’ve used to determine which apps are the best:

  • User Experience – We consider that UX is one of the most important aspects of a mobile app. A poor User Experience will lead to people uninstalling and switching to a better app. Therefore, all the games on our list have a fluid interface, few ads, and a great reward system.
  • Perks and Bonuses – Having a stable balance is crucial even when you’re playing slots for free. A slot app that doesn’t have a flawed reward algorithm, which is mainly focused around forcing the user to make micro-transaction, will result in instant uninstall and a bad reputation. Thus, all the apps we’ve covered have great bonuses and rewards for reaching specific goals.
  • Slot Variety – Playing the same slots repeatedly can become tiresome. All the free slot apps we’ve reviewed have many games available, with various themes and playstyles.
  • Originality – Since the free slots market is highly competitive, being original is nearly impossible at this point. However, there are still games that keep innovating their products and have created unique casino experiences. The other apps are either inspired by the leading products or are cheap rip-offs of real money slots.
  • Graphics – While graphics are not the most crucial element of a slot machine, it can affect the overall gameplay experience. As a result, we’ve decided to include only apps with high-quality graphics, stunning animations, and a decent user interface.

Without further ado, let’s jump right into the list of the top free slot apps on Android and iOS:
