Nice game. Reminds me of Infinite Certainty:
http://www.spaceandgames.com/?p=27 http://www.spaceandgames.com/?p=27
(now, granted there's a catch: question like 'is 89 prime' is harder than 'is 5 prime'; so it makes sense to have very high confidence of the latter (99.99% sounds reasonable) while much lower of the former)
p.s. Game over
117 = 32×13
You correctly sorted 20 numbers.
Feel I did pretty well.
- ilyanep 11y agoI got to 31 before I got tripped up on the exact same number. It looks prime!
- dylandrop 11y agoTrick: add up digits, if they are divisible by 3 so is the number. In this case 117 yields 1+1+7 = 9, and sure enough so is 117. (117 / 3 == 39). https://en.wikipedia.org/wiki/Divisibility_rule#Divisibility_by_3_or_9 https://en.wikipedia.org/wiki/Divisibility_rule#Divisibility...
- ilyanep 11y agoYeah, I had been doing that with other numbers, but somehow didn't trigger for that one. Must have been the timing pressure.
