Worms Blast is a puzzle game similar in concept to Puzzle Bobble, with several important distinctions and gameplay features taken from Worms games. Instead of releasing and matching bubbles, the player has to color blocks on a hexagonal grid. Unlike most Bust-A-Move variants, the player character can move right and left, sailing in a boat. Various weapons, such as bazooka, grenades, dynamite, and others, can be used to fire at the blocks, coloring them on impact. Like in the main, artillery-based Worms games, holding down the fire button increases the power of the weapon, affecting the distance it travels.
