I don't like that it only allows one solution. Of course, I may be missing something, but to me it looks like occasionally I'll have it solved, perfectly fine, and it says "this doesn't seem right..." and highlights 4 tiles for me to switch that shouldn't affect anything at all.

Strange, does not load for me at home using FF.

Also occasionally it won't let me click the top row.

Leopard, maybe you accidentally duplicated a row or column? That's an easy rule to forget.

Yeah, that's almost always what it turns out to be in my case...those near-duplicate rows and columns can be really hard to see on a large grid. The hint button here is nice, since it'll immediately show you the problem rows or columns if you're stuck at one of those points.

Did I miss the no duplicates rule in the tutorial? Didn't see it.

It's in there (last rule presented). It only mentions rows, not columns, so I guess you're just supposed to figure out that it's the same for both since that's how the other rules work.

This puzzle is too straightforward. There's no foresight like slitherlink. You go straight from start to finish by looking forward one turn at any step.

Identical to the Conceptis game tic-tac logic but with maybe a nicer interface. i had to stop playing conceptis completely as was too addicted.

The android link seems to be for the wrong game.

I've seen better implementations of this hitori-game...

I might have the duplicates issue, although I swear I check whenever that happens and it's not a problem. Also, it's usually 4, in a square, that goes:
br
rb
Which means they can't be dupe rows OR columns.

Why don't you take a screenshot the next time you have that problem and let us take a look?

FWIW, if I'm understanding you correctly, that actually sounds like exactly the kind of scenario where the duplicate rule would come into play, i.e. if the square were
rb
br
instead of
br
rb
then there would be a duplicate row or column somewhere, so it has to be the other.

The screenshot idea is a good one, or try this: next time it happens, just make the cells the game says are a problem blank and click the hint button to see what comes up.

Slick appearance but not a very challenging puzzle. Most of each level can be filled in using the the "three in a row" and "same number of each color" rules. The matching rule can be applied when there is a completed row or column, and a matching row or column with two empty spaces and an equal number of each color.

Yeah, I have played a few rounds where there were multiple solutions, at least for the larger grids. That's really a flaw in the level generating engine.

I'm curious how you verified that there were multiple solutions, given that the game will end once you reach a valid one. Not to doubt you, but it really does seem more likely to me that the "other" solution would have turned out to have a duplicate row or column somewhere, given how hard those cases can be to see.

BTW, if anyone feels like digging through the code to answer this question definitively, the dev has made it available here:

(Looks like the level generation code is in js/grid.js)

Nice puzzle. I have a minor hangup with the interface: the unused tiles are too dark. At times, when playing a 10x10 grid on my phone in a bright environment, I didn't notice a completely empty top or bottom row.

The computer doesn't accept every valid solution:

It's often easy to find multiple solutions identifying 2-switches, such as the above example.

Patreon VIP abfdrumz November 17, 2014 9:43 PM replied to bluemoose19

But that's not a valid solution, because columns 1 and 9 would be the same.

Very nice, very simple, nothing new. My main complaint would be needing to use full screen (or zoom out) to see the whole board. Admittedly I'm on an older laptop, but I don't exactly need that extra resolution for this game

Missed this game when it first was posted, but having found it now, I'm really finding myself sucked into a Zen-like addiction of solving these grids!

The 10x10 grids are just beautiful to put together! A very satisfying sense of completion that I can't seem to stop doing.

Oh my gosh! I've played over 50 games in a row. Wife just checked my pulse. Must....break....free...!
