By setting the snooze time to 9 minutes, the alarm clock only needs to watch the last digit of the time. So, if you hit snooze at 6.45, the alarm goes off again when the last digit equals 4. They couldn’t make it 10 minutes, otherwise the alarm would go off right away, or it would take more circuitry.

Umm… That has nothing to do with the riddles.

It is a very weird explanation especially since my alarm (along with a lot of modern clocks) has a 5- and a 10-minute interval.

This is not at all how digital clocks are built, and has no basis in reality. Electronics are not done in base 10 numbers, base 2 or base 8 (dip switches). I’ve never seen a clock built like this, and my clock snoozes for 7 minutes, not 9

but you could just watch the 10 place for the numbers and have less circuitry.
