Solitaire type of game played on rectangular board - has square and rectangular pieces to be moved to achieve required pattern

摘要

The game is played on a rectangular board with a raised frame. The ratio of length of the rectangle to its width is 5:4. There are three types of playing pieces which include four small squares (1) with the side of the square equal to one quarter of the board width. The remaining types are four rectangles (II) each equal to two small squares (I) and a large square (III) equal to four small squares. When these pieces are placed on the board a space equal to two small squares is left uncovered. The aim of the game is to achieve a pre-set pattern by sliding the pieces into free spaces.
