Big Bang Boom

Expanding Reels Feature

Every spin starts with a 4-reel, 4-row gaming grid. When symbol matches occur around the edges of the gaming grid or bombs explode, you can expand the grid. This way, you can add 3 rows to both the top and bottom of the gaming grid during the main game. When you unlock all 10 rows, you progress to the bonus game for 6 Free Spins. In Free Spins, the Expanding Reels Feature lets you add 2 reels to the left and right sides of the gaming grid, up to 8 reels.

Types of Bombs

•Vertical Bomb – Explodes vertically to remove adjacent symbols to the top and bottom of its position.
•Horizontal Bomb – Explodes horizontally to remove adjacent symbols to the left and right of its position.
•Diagonal Bomb – Explodes diagonally to remove symbols adjacent to the corners from its position.
•Plus-pattern Bomb – Explodes like a cross to remove symbols adjacent to its position on the top, bottom, left and right.
•Omni-directional Bomb – Explodes along with all symbols adjacent to its position to remove all touching symbols.
•Cluster Bomb – During the main game, it randomly explodes 3-5 brick-covered positions. In Free Spins, it explodes 3-5 positions not occupied by other bombs.
•Persistent Bomb – Only activates in Free Spins. It explodes along with all symbols adjacent to its position and persists on the reels to explode again once on each following spin until Free Spins end.
