A two faces (front and rear) rectangular form is covered by little squares which can be dragged along both faces, directly with your fingers.Actions are executed over squares in the front face although corresponding movements in the rear one can be observed in a smaller mirror image. At the beginning, little squares can be slowly and randomly scrambled (fast scrambling is also available) to establish an initial disordered position which can be reached again in the future so another competitor can play starting from the same position.Once the squares are scrambled you should drag the little squares to get the ordered position (red squares in the front face and green ones in the rear) as fast as you can (time needed is given) or using a small number of movements (the number of movements needed is also given).If slow scrambling is used you can try to remember movements carried out for memory training.Using Settings option in the main window you can configure the game so different forms are available, the number of scrambling movement can be changed, the rear face can be hided and background music can be stopped.Through Continue option you may continue a game which was previously interrupted.More details in www.sandap.comTry free version!
