Have a go at this game. 39 is my nemesis, my finger keeps being drawn to it.

103 my top score so far.

I hate you right now 😂.

I'll swap you.

51 used to be my nemesis.

I know 51 because 51 is the number that definitely should be a prime but isn't, where 39 obviously isn't a prime because it clearly divides by 3 so what my brain is thinking when it keeps going 'oooh 39' is beyond me.

What's your high score on your game, kitten?

156

113...

My brain doesn't see 2 as a prime, and wants to click 9. More practice needed 😁

Thanks for the game OP! My score is pitiful, so I'll try again now.

57 can also get in the bin.

I’m too cautious, so keep running out of time. Need to speed up!

Both good suggestions, thank you. 111 is my max so far. 57 is my nemesis, even though I KNOW it!!

This is highly addictive.

Thanks @noblegiraffe love this!
My best score is 104 so far

Great game and deffo addictive thanks @noblegiraffe 😂

Love this!

64 my best so far

I always find it confusing that 1 isn't a prime number - failing instantly!

I think it's because a prime number has to have 2 factors, and 1 just has itself.

I think that's the reason anyway!

1 used to be considered a prime but it needs excluding from the primes because otherwise the Fundamental Theorem of Arithmetic which says that every integer greater than 1 can be expressed uniquely as a product of primes wouldn't work. E.g. 10 = 2 x 5 is unique, but if 1 were a prime you could also have 10 = 1 x 2 x 5 or 10 = 1 x 1 x 2 x 5 and so on.

The 'prime numbers have two distinct factors but 1 only has one' is a definition deliberated fudged to exclude 1.

I failed on my first click at 1 🙄

Best score is 62 after 5 minutes...very addictive!

Argh!!!!

I knew someone would know the real reason haha

Thank you noblegiraffe for the thread!

I'm still working on that Noble

Thanks for the explanation @noblegiraffe

Still trying to break 100, but great game!

Thanks for this. Can't go to work now as I'm addicted and need to get into the 100s

Damn you for this 🤣

Does your high score reset every day? I got 96 yesterday (trying to hit 3 digits), but back to zero this morning.
