• Start from
• Close into a 2x2 square with four stacks of two tiles each organized in three levels
• Position it such that the two East stacks have first and second floor, whereas the two West stacks have second and third floor. The North-West top (third floor) tile is of type slash
• Turn (down) 180 degrees the flap tile located at bottom (first floor) of the North-East stack
