A feature that expands the game board and increases the ways to win by removing 'blocker symbols' that obstruct parts of the reels.

Blocker Removal is a feature where parts of the reels are obstructed by inactive 'blocker' symbols at the start of the game, and these blockers are removed through specific in-game actions to progressively expand the game board.

The core of this feature is to provide the player with a clear mission of 'unlocking closed spaces to win bigger rewards', and to give the visual fun and sense of achievement of watching the game board grow.
