Promatic Games debuts its new LOCK & ROLL™ feature with the launch of Calavera COINS, a Día de los Muertos-inspired slot themed around Mexico’s iconic skull art tradition. This feature introduces an exciting Re-Spin mechanic with collectible locked symbols. Players can unlock a Jackpot prize by gathering all symbols-delivering the popular Hold & Win bonus experience.
The Calavera COINS game is built as a 5×3, 10-line slot where the key symbols – including decorated skulls and festive iconography – reference the aesthetics and symbolism of the world-famous Mexican holiday.
“LOCK & ROLL™ brings a new dynamic to our games – it adds rhythm, tension, and a greater sense of excitement to every spin. We are thrilled to introduce this feature to our online portfolio and soon also to our land-based cabinets,” said Luka Oblak, Head of Product Development at Promatic Group. “Calavera COINS is more than just LOCK & ROLL™. From a visual standpoint, it is one of the best games we have ever produced – fully designed by our in-house team.”
The LOCK & ROLL™ feature is activated when six or more BONUS symbols land on the reels. The triggering BONUS symbols remain fixed in place, while all remaining positions re-spin three times. Only BONUS symbols are active during the feature – all other symbols are disabled. Every new BONUS symbol that lands resets the re-spin counter to three. The round continues until no additional BONUS symbols appear or the entire grid is filled. When the feature concludes, the values of all BONUS symbols on the screen are added together and paid as the bonus win.
If all 15 BONUS symbols are collected, players receive an additional 1000x total bet on top of the accumulated BONUS symbol values, activating the Grand Jackpot.
For now, Calavera COINS will be available exclusively in Poland, with further market releases planned in the future. Promatic Group has also confirmed that the LOCK & ROLL™ feature will soon be implemented in its land-based slot machines, ensuring a unified experience across all game platforms.
