Ball Push Puzzle
How to Play
The aim is to restore the strings of coloured balls by pushing them round the circular tracks.
Mix to begin the game. Click on a ball to push them round. Solve does as it says.
The puzzle idea came from William Churchill in 1891 using 42 balls which he patented in the US.
Later, mathematician Endre Pap produced ‘Hungarian Rings’ using 38 balls as here.
