Daruma-Otoshi ダルマ落としを高 Darumaotoshi or "falling daruma" is a game of skill where you stack the wooden pieces with the meditating daruma head on top using the wooden mallet pushed through the holes in the circular pieces. Next pull out the mallet and try to hit one of the pieces with the wooden mallet so that the pieces drop but stay stacked in a column. If the pieces drop on top of each other and don't collapse you win!

haha,just a game~
