Slot Machine Software


Slot machines are designed and offered by a wide range of companies. New online slots are being developed and introduced on an almost daily basis.

Online casinos use software from these companies to offer games you can play. Some casinos only use a single software provider, while others use multiple software providers.

On this page we list the most popular online slots software providers that we recommend. You can learn a little about each company and some of the popular games they offer in the sections below.

What to Look for in a Slots Software Platform

One of our goals at is to help you find safe places to play online slots. This includes reviewing games offered by legitimate companies that have tested and fair games. Here are a few things we consider when choosing software companies to review.

  • How long has the company been in business?
  • Are their games and RNG system tested by a legitimate testing company?
  • Do they have a track record of quality games and customer service?

The good news is we only review games from trusted platforms, so you don’t need to spend hours researching the safety and reliability of each company.
