ATG Casino marked a significant moment for its online gaming platform after a player based in Solna, Sweden, claimed more than €1.4 million from a MEGA Jackpot. The payout stands as the highest single prize in the operator’s history and came through a jackpot system supplied by EveryMatrix. The win occurred on the Starburst slot, a long-running title with strong popularity across Scandinavian markets, after the jackpot climbed to an unprecedented level shortly before it was released.
Record Payout Triggered On A Popular Slot Title
The jackpot fell on Starburst as the MEGA tier reached its peak value. The timing placed the payout among the most notable slot wins recorded by the operator. The system behind the prize relies on JackpotEngine, which links jackpots directly to games and updates their value in real time as players participate. Visual elements embedded within the game interface display jackpot growth continuously, allowing players to track changes as they play.
Operators using the system can attach as many as four jackpots to a single game while keeping standard wager levels unchanged. The platform also includes simulation functions that allow operators to estimate how often jackpots may be released, supporting long-term planning around prize distribution.
Jackpot System Design And Engagement Features
JackpotEngine connects with both proprietary titles and externally supplied games through an aggregation framework. This setup allows a single game to feed into more than one independent jackpot, each defined by its own starting amount and contribution percentage. The structure offers flexibility in how jackpots are built and maintained across different games and player segments.
The system also links directly with a wider engagement platform that introduces added features beyond the base game. These include short-form games, competitive formats, structured challenges, and bonus mechanics. A layered loyalty model allows jackpots to vary depending on a player’s loyalty tier, creating different prize paths within the same ecosystem.
Stian Enger, CEO of Casino at EveryMatrix, said: “This headline-making win is the perfect showcase of the power and excitement of our jackpot technology. It shows how JackpotEngine can deliver truly life-changing moments for players, while giving operators flexible, engaging tools that elevate the casino experience.”
