A tour puzzle is a puzzle in which the player travels around a board (usually but not necessarily two-dimensional) using a token which represents a character.
Sometimes the player has more than one token with which to travel.
In the case of large hedge mazes, the player makes the trip themselves instead of a token.
Often there is a given start and finish position for the player's token.
Some tour puzzles demand that certain points on the board have to be visited on the way.
