Technical Specifications

Merge Up Mechanics

The core mechanic strips away traditional paylines. Four or more adjacent symbols form winning clusters — but instead of simply paying and vanishing, they merge upward into higher-value symbols. A cluster of 4–5 symbols creates 2 upgraded versions. Six or seven symbols produce 3 upgrades. The progression runs from symbol 0 through 8, with level 8 merging directly into Scatters.

Technical Specifications

Random Multiplier System

Each spin assigns random multipliers between 1x and 99x to the four gem symbols — snake, griffin, minotaur, dragon. These multiply only wins containing that specific gem. The banners on the left display current multipliers. When you land a winning combination with, say, the purple dragon at 47x, that 47x applies only to that symbol’s payout.
