Stackways slots: the Mayan blueprint and Ronin risk reset
Stackways began in 2023 with Mayan Stackways, where Hacksaw Gaming fixed the line's identity around stacked and splitting symbols, reel-set changes, and bonus access on a 5x6 grid. Its 1,024-way structure combines high volatility with Hold and Spin, Hold and Win, reel modifiers, and a 10,000x maximum.
Ranked by Slot Score
| Game | Year | RTP | Volatility | Slot Score |
|---|---|---|---|---|
 Mayan StackwaysHacksaw Gaming | 2023 | 96.23% | High volatility | 83 |
 Ronin StackwaysLatestHacksaw Gaming | 2023 | 96.35% | Low volatility | 71 |
Later that year, Ronin Stackways compressed the grid to 5x4 and reversed the volatility profile from high to low. It retained stacked and splitting symbols, reel-set changes, Bonus Buy, and the 10,000x ceiling, but introduced mystery symbols and stepped away from the Mayan game's hold-style feature load. The series therefore expands by changing the pressure around its shared Stackways tools: Mayan favors a sharper bonus chase, while Ronin applies the same symbol framework to a lower-volatility rhythm.
