Every slot, roulette wheel and live blackjack table you play is built by a specialist software studio — the game provider. These companies design the games, set the RTP, run the maths and (for live casino) operate the studios with real dealers. The casino simply licenses and hosts their content, so the quality and variety of a casino comes directly from the providers it works with.

The biggest names you will see again and again include Pragmatic Play, NetEnt, Play'n GO, Nolimit City and Microgaming for slots, plus Evolution and Pragmatic Play Live for the live-dealer experience. Alongside them sit dozens of boutique studios that bring fresh themes and innovative mechanics to the lobby.

A strong, varied provider line-up is one of the clearest signs of a quality casino. You can see which studios each casino works with in the "At a Glance" section of our casino reviews.
