The design is organized around color-coded Crystal Scatters, each tied to a distinct feature path. Every color is paired with a matching skull display and feature path: green for Upgrade, blue for Expand and red for Multiplier, and each feature awards seven spins as standard.

Each path alters a different part of the math model. Upgrade Free Spins turns Bison symbols into Thunder Bison that pay twice the standard value, while Expand Free Spins opens the grid to five reels by six rows and 7,776 payways. The third path introduces multiplier wilds to the middle reels.

The strategic detail is what happens when features overlap. When two feature types activate together, Super Charged Free Spins combines both sets of mechanics, and when all three activate, Mega Stampede Free Spins brings the six-row grid, Thunder Bison and Multiplier Wilds into the same seven spins.

This latest operation forms part of an ongoing surge in Türkiye’s efforts to curb illegal betting throughout 2026. 

Earlier this year, Turkish Interior Minister Mustafa Çiftçi called illegal betting a “scourge that corrupts society” and emphasised a move towards tougher enforcement.

According to Çiftçi, the rapid growth of digital payments and cryptocurrencies has transformed illegal betting into a major conduit for money laundering.

As work on Game in a Box progressed, Yggdrasil began to see an opportunity extending beyond its own production process.

Historically, building a game studio meant putting all the necessary components in place – from developers and mathematicians to QA and compliance, as well as the underlying systems and integrations. Alternatively, a business looking to enter the market could acquire an existing studio.

Both routes require significant investment. However, as Curwen, adds: “There are plenty of people in this industry with great ideas, brands, audiences or distribution who don’t want to build an entire slot studio from scratch.”
