A black (filled) dot between two cells indicates that the digits in those cells are in a 1:2 ratio. Dots - As in Kropki Sudoku, a white (unfilled) dot between two cells indicates that the digits in those cells are consecutive.The colors are simply for clarity in the middle square, all four arrows proceed straight through the center to the opposite side. Multiple arrows emanating from a single circle each individually add up to the circled number. Arrows - As in Arrow Sudoku, the numbers along an arrow sum to the number in the circle.This puzzle is definitely a Sudoku, with the following indicators: I hesitated to enter this in the Escape Room FTC, but I definitely was inspired by the challenge to create this puzzle, and it is, in some sense, an escape room. The second one had such a clean path to its solution that it will be remembered.An entry in Fortnightly Topic Challenge #50: Escape Rooms The first one had a neat killer feel to it, and I felt that a necessary step was one I had never seen before in an Arrow puzzle. I will say that both Sum puzzles were terrific. Of course it's very possible I just don't see the logic-based steps. Until today, I had never ever torn up the page in a fit of absolute rage upon finding an error, so that must mean something! : ) It is uncommon for a LMI sudoku test to have what feels like many necessary bifurcation steps, and in that sense I guess I am surprised.

Having said this, I found the Missing Arrow EXTREMELY difficult/impossible/guess-y (as did nearly everyone else ) and the Parted Arrow felt similar to me (although 25 people solved it so I must have missed something, as usual ). Rohan, there were some exceptional puzzles in here and you deserve many congratulations for putting together such a clever set! Rarely does a sudoku really get the mind working so hard for so long, and for the designs to be so nifty is a nice touch as well. So it is close to the 'Submit' button, but not dangerous. If you have entered only half of the sudokus, and you click on 'Claim Bonus', the sudokus will be submitted, and nothing else will happen. Once all your sudokus are submitted (either paper mode or online mode ), it pops up the 'Are you sure' dialog.

In Sudoku test, it remains enabled all the time, and it works like 'Submit'. ( Of course, this test didn't have online mode, but. But in Sudoku test, we don't do that because players could be solving/submitting online. It also has a 'are you sure' dialog afterwards which always costs me another minute of bonus as I keep forgetting it exists and losing 3 seconds to go over a quanta of minute.ġ ) In a puzzle test, we deactivate the button until all puzzles are 'filled in'. In other words, while it is there to click on, it cannot end your test until you could possible have a bonus to have. I can't comment on this test since I didn't finish, but on the last few tests I've caught that this button is not 'active' until you have enough correctly formatted answers in the system. I noticed the CLAIM BONUS button is dangerously close to the SUBMIT ANSWERS one, a couple of times I nearly hit it by mistake, better to move it a bit out of the way, at the end of the day it has to be used only once. Pity I wasted a lot of time to no avail on one of them (found the correct solution later ). So, even if a player types '80' instead of '08' (maybe due to quickly typing it from the paper ), it is as good as correct. For example, an arrow over two cells may have 0 and 8 in its circle. As long as you get the two correct digits in the circle, it is ok for me. Of course, you will get a unique order of the two digits inside a circle while solving.īoth orientations are accepted as correct 'answers' just for convenience of players.

My other idea for the reasoning would be that some circles have their digits given, but not necessarily in the right order and people might forget to change it when putting in the answer key.Įach circle has exactly one arrow. And I would assume if the sum of each circle is unique, it would be more logical to just accept only the correct sum for the circle as an answer.

I was wondering this because the instructions says both orientations would be considered correct. If so, can the sum change over the different arrows? Say, a circle has the digits 1 and 2 in it, can one arrow sum to 12 and the other sum to 21?
