Not a big fan of prime numbers, but this one was fun

Obviously I love love love Rat Run, but I'm very happy pickup sticks are back :)

That was nice. I really like logic with prime numbers. Thanks!

Egads! This puzzle is WAY harder than its 2* rating, at least 4*. Tricky break-in, tricky logic deductions to make at the mid and late parts regarding parity... you need to know all the tricks of the trade.

Whew!
I found this one a lot harder than the consensus (and than other pickup sticks). 4 stars for me; must be the heat.
Nice though!

Pick up sticks, yay! very straightforward if you manage to keep the facts about prime numbers in your head, which is the tricky part lol

Clever puzzle as always, Marty! Agreed, this is somewhere between a 2 and 3 star. Got stuck for a while trying to figure out the last big "trick" to unlock the end of the puzzle. Very fun!

High end of 2* or lower end of 3* honestly, depending on your math affinity.
Very nice puzzle nonetheless

Love this puzzle as well as the whole series! But for me this one is probably 4 stars difficulty

Thank you very much for creating and sharing another beautiful addition to your other famous series. 2* seems okay - if you know your primes!
