Despite initial excitement, Big Time Gaming’s Megaclusters engine has not become as popular as expected, especially when compared to their Megaways engine. However, the new Millionaire Rush Megaclusters game could change that. The game’s branded gameshow concept is easily recognizable and its Megatrail™ feature, which triggers unpredictable modifiers, offers a refreshing change. The game requires 5+ matching symbols anywhere on the grid to win. Each win triggers the Reactions mechanic, replacing each winning symbol with 4 smaller random symbols. The Megatrail on the left has 12 rungs, each containing a modifier, feature or blank. The Bonus Round triggers when reaching the 7th rung on the Megatrail, awarding 6 free spins. The top rung prize can reach 2,000x your stake, and at least 6 random modifiers on the Megatrail per free spin are guaranteed. Despite the generic gemstone symbols, Millionaire Rush Megaclusters is exciting and unpredictable. The potential of the game is huge, with the possibility of winning up to 55,260x your stake. Other games in the BTG range include Star Clusters Megaclusters and Cyberslot Megaclusters, but Millionaire Rush Megaclusters could be the game to bring the concept into mainstream popularity.
