I tipped my hand a bit in challenge #3 when I mentioned that CodinDice may be the next challenge. Either I was anticipated (and my timing is off) or through sheer coincidence...
CodinDice is currently the Puzzle of the Week, and consequently has gained enough solves to be bumped lower on my list. Not much lower, though... That must be one tough nut to crack! It currently clocks in at #8:
CodinDice - 122 days, 19 solved - 0.16
So enough with the preamble! What's the challenge this month? Here's the current top of the list using my solutions per day formula:
Ticket to Ride: Europe - 52 days, 3 solved - 0.06
Haunted Manor - 304 days, 24 solved - 0.08
Einstein's riddle solver - 159 days, 22 solved - 0.14
Well, Ticket to Ride: Europe has shot up to the top of the list due to an unprecedented lack of solves (who wrote that joke of a puzzle?) But it's a bit fresh yet. Let's let it stew for a while.
Skipping our old favorite, Haunted Manor, next up is the very nicely designed Einstein's riddle solver. This puzzle takes the classic pencil-and-paper logic puzzle and provides it in a software-friendly format. Very fun.
Here's the current list of Einstein's riddle solver solvers' published solutions:
Want to join those puzzle champions on the list? I'm pretty sure you can. Einstein's riddle solver is tough, but if you apply yourself, I'm sure you can handle it. Give it a shot!
