What is the trick to slide puzzles?
One strategy you can use is to free up your goal location and move the target piece in that direction by moving all the pieces in the way, too. Then make a full&a;quot;circle&a;quot; again and again until the last piece of the chain, which is your target piece, reaches its location!
Who invented slide puzzles?
The oldest known slide puzzle was invented in 1880 by Noyes Chapman, however, in some records, Sam Loyd is credited as the inventor.
