Connect the dots

Versions for older solvers frequently have extra solving steps to discover the order, such as those used in puzzlehunts[2] and the connect-the-dots crosswords invented by Liz Gorski.

The roots of connecting dots to create pictures or help with calligraphy can be traced back to the 19th century.

The emergence of connect the dots games in the printed press takes place in the early 20th century.

While the first books containing connect the dots games exclusively were printed in 1926 by Ward, Lock & Co.[4]The phrase "connect the dots" can be used as a metaphor to illustrate an ability (or inability) to associate one idea 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.
