About Slotmill

Slotmill is a relatively new software game developer that was started by a group of industry veterans in 2019. The main aim of this group was to create premium online casino games, that include both 3-reel and 5-reel online slot games.

Slotmill’s main focus lies in pushing the boundaries of innovation and technology to deliver high-quality content. The company’s motto is ‘Great Games Don’t Come by Chance’ and this is true since all of the games are embellished with vibrant graphics and features that make them stand out.

Unlike most slot games that weigh in at 30-50 MB, Slotmill delivers AAA-class games with full HD graphics that are well below 10 MB. This not only minimises load times but also allows for more games to be included in in-store apps.

Slotmill games incorporate two main features for added thrills. First, there is the Burst Mode, which is an enhanced autoplay feature with more than two game rounds per second. Then there is the Fast Track feature, which allows players to directly access bonus features without the need to grind through regular gameplay.
