The Mensa Puzzler Alarm Clock requires the user to remember the sequence of lights to stop the alarm

The solution to getting up on time! It may not be most people's idea of fun, but this is the ultimate gift for those who simply refuse to get out of bed. The digital alarm can only be turned off after a random sequence of lights has been memorised and repeated by its sleepy-headed owner. If they are too slow or incorrect, the alarm sounds even louder and continues until they get it right. It is possible to 'wimp out' but 30 seconds of extra loud alarm has to be endured as a punishment. All very sleep shattering - there are three levels of difficulty so even the most snoozy have no choice but to jump start their brain to restore calm and silence. Devilishly devious! Developed in conjunction with Mensa.
