Overview

Slotmill is an online slot studio founded in Sweden in 2019. Johan Öhman founded it and serves as CEO, and a team of about 20 works out of Stockholm. Its first game was Star Spell, released in July 2020.

Under the motto “quality over quantity,” it releases only around 10 games a year and prefers high-volatility games. Its catalog has more than 50 games.

Licenses and Markets

In June 2021, it received a B2B supply license from the Malta Gaming Authority (MGA), which lets it supply games to any casino holding an MGA license. The founder described this license as a “seal of trust.” It also holds a Curaçao license and has signed a supply agreement with ATG, the Swedish state-owned horse racing and gaming company.

Proprietary Features

FeaturesDetails
Fast TrackJumps straight into the bonus feature
Burst ModeAn auto spin mode that spins rapidly in succession
Fixed RTP™A policy of supplying only certified fixed-RTP versions so the RTP cannot be changed
True Reels™A policy that has the demo and the real game use the same reel setup and math model

Fixed RTP and True Reels can be read as a way of distancing the studio from the practice of RTP varying by casino (RTP versions).
