In Tower Builder, the world of PebbleWorld abounds -- a land full of magic and intrigue where pebbles are like human families complete with adults and children. They live together underwater, on land and even in the sky. When one wayward pebble loses his way on a journey full of unexpected obstacles, you'll help him get back home by creating new stones and pathways for him. You'll use a concrete mixer to mix new stones and use special stones to create connections with others. You'll climb mountains, cross abysses and build up intricate constructions.
