Very open-ended puzzle this month! The best solution we found to this month’s puzzle, along with 10 of you, had a cost of about 0.7082. There are actually a couple of ways to achieve that cost, but one is:
(a4,c3) (k2,d6) (t7,d8) (e1,j6) (t7,j8) (q12,r4) (i8,r12) (l15,r18) (s19,t20)
Here’s a video illustrating what that solution looks like:
Congratulations to everyone who found a valid path!
