It is really hard when you get numbers over 100. Here is a hint: numbers are divisible by 3 of the sum of the digits is a multiple of 3. For example 51 = 5 + 1 = 6, which is a multiple of 3. Another example: 93 = 9 + 3 = 12, which is another multiple of 3.

It gets easier after you try it a few times. You start to memorize more prime numbers. The clock pressures you to decide too fast, though!

I agree. I'm glad it is only for one minute! If they didn't have a clock I think it would be much easier.
