How we rate the best slot apps
We use specific criteria to evaluate slot apps. While we did take note of customer reviews on the app stores, they weren’t a major factor in our review process.
Instead, the main factors we consider are:
Free spins and welcome bonuses: We consider whether welcome offers are accessible, easy to understand, and generous and whether there are any restrictive terms, such as wagering requirements.
Game selection: Our recommended best slot apps should have a wide variety of casino games to complete the best online slots from reputable providers.
App performance: We want any app to be fast, easy to use, and reliable while taking up as little memory as possible. In addition, we consider whether it is an all-in-one app, or if the casino has a dedicated slots offering.
Payment methods: Our recommended slots app needs to offer a range of quick, easy payment methods for both deposits and withdrawals.
Customer support: We take into account the quality and response times for customer support offerings.
