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
| Features | Details |
|---|---|
| Fast Track | Jumps straight into the bonus feature |
| Burst Mode | An 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).
