Symbol Upgrade is a powerful feature that progressively converts low-value symbols on the reels into higher-value ones as the game proceeds. The core of this feature is not just a one-time symbol change, but a 'growth' structure where lower-tier symbols are permanently removed from the reels and replaced by higher-tier ones. This drastically increases the average expected payout of the reels towards the end of the round.

A Multiplier Symbol is a special symbol that doesn't form winning combinations on its own, but provides a random multiplier value just by appearing on the reels. The core of this feature is its role as a 'seasoning' that amplifies an ordinary win into a massive prize worth tens or hundreds of times more when it appears alongside a regular win.
