INSULOT, an edutainment tool on cellular phone is a three-window slot machine which is designed to teach the relationship between plasma glucose level, amounts of carbohydrates, and insulin dosage. The INSULOT provides pre-prandial plasma glucose level and type of food. A player estimates an insulin dosage to achieve an appropriate postprandial plasma glucose level on the slot machine. INSULOT, then, simulates postprandial plasma glucose level. Expected to be used for kids age 10 and up.
