Swedish studio Slotmill launches Halloween slot Ribs’ Golden Crypt

By Mikael Sandberg · Published 21 October 2026

Swedish game studio Slotmill has released a new Halloween-themed slot called Ribs’ Golden Crypt. The game launched on 20 October 2026 and is already available at Swedish-licensed casinos.

Here’s what’s new

Slotmill has launched Ribs’ Golden Crypt, a playful and spooky game released just in time for Halloween, with an RTP of 96.01 percent and a maximum win of 10,000 times the stake. The game has a gothic Halloween theme and is played on a 6×6 grid with Cluster Pays mechanics, with stakes ranging from 0.20 to 100.

The main character is a skeleton king who has lost the keys to his own treasure crypt, and players help him find his way back through wins on the grid. The game mechanics rely on Avalanche wins where new symbols fill empty spaces after every win, while Giant Symbols and meteor multipliers can build up during the round. Free Spins are described as the strongest part since a persistent multiplier can carry progress across several spins. On top of that, the game features free spins, multipliers, scatter symbols, extra free spins, a buy-in feature and a special 3×3 Mega symbol.

What it means for you as a player

Having Slotmill behind the game offers extra reassurance for Swedish players. Slotmill has established itself in the Swedish gambling market and holds two licences from Spelinspektionen, valid until 30 June 2028, guaranteeing that the games are legal and safe to play in Sweden. The studio was founded in Sweden in 2019 by Johan Ohman, former CEO of NetEnt.

In practice, this means you can find Ribs’ Golden Crypt among several online slots at Swedish-licensed sites, without leaving the protection the licence provides. Keep in mind that high volatility means wins can take a while to appear, but can be larger when they do. If gambling starts to feel like a problem, help is available via Stödlinjen.se, and you can always pause your play across all licensed operators via Spelpaus.se.

The bigger picture

Slotmill releases roughly 10 to 12 video slots a year and focuses on sharp visual design rather than a wide catalogue, with full HD graphics built on HTML5. That makes each new release something of an event rather than part of a conveyor belt of titles. The studio is certified to offer its games in, among other markets, Sweden, and has released around forty slots since its debut title Star Spell in July 2020.

Ribs’ Golden Crypt joins a wider trend where several studios compete for attention ahead of Halloween with spooky themes and high volatility numbers. For Slotmill, a studio that has built its reputation on quality over quantity, it’s further proof that the Swedish studio continues to keep pace with the bigger players in the market.
