Here's an original game that my daughter has had its 4 years and 4 years later, we're still playing. The smells are still there although present (2 year warranty by the manufacturer). Admittedly odors small boxes: fruit smells, flowers, plants, soap, sea grass, fireplace, mushrooms ... As much as some are easy others pose much of problem. An excellent game that develops the olfactory sense of young and old having fun just as much.
