Four white markers are placed on the first four squares of a row of nine squares. There is a space of one square and then four black markers.

  • White markers can only move right.
  • Black markers can only move left.
  • Markers can move forward one square, or can jump over a marker of either colour if there is an empty square to land on.
  • Markers are not removed from the board if jumped.
  • You DO NOT have to alternate moving black and white markers.

How can you get the markers to exchange places?
