Grasshoppers Quadrille

## Description

_Grasshoppers Quadrille_ is a single player puzzle, it is played entirely
with the mouse.

This puzzle was first described in Henry Ernest Dudeney’s book _536 Puzzles &
Curious Problems_.

The game takes place on a 7 x 7 board. On this board the central cell is empty
and the remaining forty eight cells are filled equally with red and blue
tokens. The red tokens are on the left hand side and the blue tokens are on
the right with the central column being split between them.
Red tokens can only move down and/or to the right, blue tokens can only move
left and/or upwards. The object of the game is to exchange all the tokens so
that the red tokens occupy the cells formerly occupied by the blue tokens and
vice versa
