Patent abstract
When an operation block collides a stacked block in an X-direction, a part of the stacked block facing an operation block is shifted to the X-direction to allow the operation block to be absorbed in the stacked block and an end being opposite to the end facing the operation block of the shifted stacked block to be ejected from the stacked block. The ejected block can collide with the stacked block again as an operation block. Such a collision operation is repeatedly performed after the completion of a predetermined arrangement in the stacked block.
