Step-by-step explanation:
The three popular variations of gobstones are Classic Gobstones, Snake Pit Gobstones, and Dragon's Breath Gobstones. Gobstones is a game that has similarities to the muggle game of marbles, with the added twist that the gobstones can squirt a foul-smelling liquid into the face of the opposing player when they lose a point.
Classic Gobstones is the traditional form of the game players enjoy, while Snake Pit Gobstones changes the game's dynamic by having a board with trenches, requiring players to be more tactical. Dragon's Breath Gobstones introduces another layer of complexity with gobstones that emit a harmless but distracting puff of smoke, challenging players to maintain their concentration under harder conditions.
