亀田のおせんべい神経衰弱 (Kamedano Osenbei Shinkeisuijaku)

Players lay out the cards and turn over two at a time, trying to find matching rice-cracker designs. The set uses 13 varieties of Kameda Seika rice crackers, with some flavor variants intentionally difficult to distinguish.

The game follows a simple memory-pairing format for children and adults: players reveal cards, remember their positions, and collect matching pairs.
