Online slots are developed by dedicated game studios, made up of graphic artists, software engineers, programmers and mathematicians, who all work together to produce the slots that we eventually play on our laptops or mobile phones. Some people are surprised to learn that game studios don’t actually operate online casinos. In fact, they just focus on creating games, and leave the running of casinos to specialist operators. You will certainly recognise some of the biggest studios: Platform providers are responsible for distributing games on behalf of studios, and act as a sort of middleman between game developers and casino operators (you might also see them referred to as games aggregators).
