To beat the hedge boss in the game, you need to focus on solving entire rows and columns.
Here are some steps to help you beat the hedge boss:
Focus on solving entire columns (vertically) or rows (horizontally) to remove one of the boss's lives, before the boss covers more space on the grid.
Remember that the number of lives of the hedge boss is changeable.
This means the hedge boss may have more lives to begin with, so you need to keep solving tiles and removing entire columns or rows to weaken him.
Be strategic in your moves and plan. Focus on creating matches and combos that can clear multiple tiles at once.
Use power-ups and bonuses that can help you clear more tiles and damage the hedge boss. For example, you can use a paint roller power-up to clear a large area of tiles.
