Bright as a Peg

An exhibit table with a information panel, sits in front of two walls. On the table lays a rectangle shape with pegs sitting on top.
a blue and orange exhibit table with a yellow, white and green information panel, sits in front of two blue and green walls. On the table lays a blue rectangle shape with black and white pegs sitting on top.

Making patterns of movement more efficient can be achieved by modelling through puzzles.

How it works

Black and white pegs need to be moved around a board in a minimum number of moves to create a new pattern.

Things to try or ask around the exhibit

How many moves does it take you to change the pattern to this? A good score is 50 moves.


This puzzle seems simple, but finding the least number of moves is very difficult. Mathematicians can spend a long time trying to solve problems like this.
