What is Twenty One?
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.

Both LiveScore and Tombola, who were a part of the original 10 operators to receive a licence, exited the market in 2024.
Compared to the 2021 licensing round, the KSA adopted a more granular and stringent approach to its licence renewal process. This was expected following new policy rules set out by the regulator in September 2025.
