Dot-to-dot puzzles can range from being a simple connection of 10 dots to hundreds of dots, ranging in difficultly due to the clutter of numbers and visible options for the connection of the dots. There are many puzzles geared for adults, making them more challenging, such as the Extreme Dot to Dot puzzle book series.
Connect-the-dot puzzles are a series of numbered or specifically placed dots that must be connected by lines to form a picture. The name of these puzzles comes from being able to see the bigger picture and joining smaller details together to form it. Being successful with such activities means one is able to associate one idea with another.
