Daruma Otoshi or darumaotoshi is a traditional Japanese game of skill where round blocks are stacked on top of one another in a single column. At the very top, a daruma sits, meditating. Otoshi means falling.

In kind of a Jenga-like fashion, the object of the game is to hit the bottom piece, one at a time, with the mallet, such that the pieces on top do not fall over.

I remember growing up with these toys. They would come out during special occasions and whenever we didn't have our Gameboy's around.

The model measures around 7.75 inches tall by 2 inches in diameter when the mallet is holding the five blocks in place. This model can be scaled up pretty easily. For extra strength be sure to print the hammer with a higher fillrate.
