Questions about slot software

Where can I find games by my favourite slot providers?

Each casino has separate partnerships with slot providers, meaning that while some casinos like Videoslots offer over 3,500 games, others may only have a couple of hundred. 

Our slot software categories contain a curated list of 10+ sites offering the provider’s portfolio. Alternatively, you can often find a list of developers at the bottom of the home page or by filtering the lobby.

Does every slot developer offer free to play demos?

Each software has a different style, features and rules, so if you’re reluctant to spend money on a new slot game, we recommend trying demo versions of a slot title. 

You can sometimes find play-for-free games at the slot providers official website. Otherwise, many casinos like Casumo and PlayOJO offer free-to-play options in the lobby. 

How many slot providers are there?

There are currently over 110 slot providers available in the UK.

Some developers have huge portfolios of over 500 titles whilst smaller independent companies only produce a couple of games a year.
