Dynamite is a special resource in the game. It can be purchased from the store. To find it, you just need to tap on the "Cart" button in the lower right corner of the screen, in the "Energy" section. Sometimes you may also find dynamite that had already been placed on the islands.

Every type of dynamite has a different price. Small dynamite can clear a smaller part of the island, while big dynamite can be used for bigger areas. The area affected by the dynamite will be highlighted yellow. To cause an explosion, you first need to pay rubies.

Once you've chosen the right place and applied the dynamite, the explosion will begin. Please note that rubies are deducted only after you have placed the dynamite, so you need to choose the position carefully as you can't change it after it has been selected.
