Connect the dots (also known asconnect-the-dots,dot to dot,join the dots orfollow the dots) is a form ofpuzzle containing a sequence of numbered dots.[1] When a line is drawn connecting the dots the outline of an object is revealed. The puzzles frequently contain simpleline art to enhance the image created or to assist in rendering a complex section of the image. Connect the dots puzzles are generally created forchildren. The use of numbers can be replaced with letters or other symbols. Versions for older solvers frequently have extra solving steps to discover the order, such as those used inpuzzlehunts[2] and the connect-the-dots crosswords invented by Liz Gorski.[3]
The roots of connecting dots to create pictures or help with calligraphy can be traced back to the 19th century. TheNine Dots Puzzle is the first known puzzle game where the player has to connect dots. But in this variant the goal is not to draw a picture, but to solve alogic puzzle. The emergence of connect the dots games in the printed press takes place in the early 20th century. These games were published with other puzzle games as pastime for children on theSunday edition. While the first books containing connect the dots games exclusively were printed in 1926 byWard, Lock & Co.[4]
The phrase "connect the dots" can be used as ametaphor to illustrate an ability (or inability) to associate oneidea with another—to find the "big picture", or salient feature, in a mass of data;[5] it can mean using extrapolation to solve a mystery from clues, or else come to a conclusion from various facts.
The Connect the Dots drawing technique ofGPS Drawing involves recording an artists GPS data only at certain points along the route. This can give the image the appearance of a dot to dot puzzle as most of the lines are straight no matter the geography of the area.
Reuven Feuerstein features the connection of dots as the first tool in hiscognitive development program.[citation needed]
Thetravelling salesman problem asks what numbers to assign to a set of points to minimize the length of the drawing.
