This sweet little vintage "magic dice" game, made in Japan, is the perfect size to keep in your pocket for a brain-teasing diversion while on the go. I love the packaging, especially the lid of the box, announcing this as a "a clever and intricate game puzzle," and the colorful set of instructions, printed on rice paper and folded up neatly to store in the bottom of the box. These outline a series of different challenges for arranging the blocks, a bit like Sudoko.
Box measures 3" x 1" x 1". These were never used but there is a bit of smudging to the paint on the blocks, original to their making.
