A feature where multiple reels merge to spin and stop together as one giant symbol.

A Mega Reel is a powerful and visual feature, primarily used in free spins bonus rounds, where multiple individual reels (usually the central reels 2, 3, and 4) physically merge to operate as a single reel that lands one giant symbol.

The core of this feature is to dramatically increase the probability of completing high-payout winning combinations by having a single giant symbol dominate the key area of the game board.
