More than One Solution

[Tanner]

Some of the puzzles have more than one solution.
A logic puzzle should only have one solution.

For example: Nonograms and HexCells.

Was this your intention?

[Enlash]

No. If you found more than one solution let me know as soon as possible.

Here are three for examples of levels that can be finished by marking either of the circled squares.

There are other levels with similar occurances..

[Enlash]

Hmm, I will take them out. Looks like they are cases of extra squares or missing grey squares.
If you find any other ones please report.

I just installed the update that fixes the three levels.
Unfortunately Level 8 still has two separate solutions.

Only checked until level 12 .. there are for sure many more but personally i don't think its such a bad thing. Do you really want to know all of them?

Are all these multiple solutions cases of just one square being changed? Because if it is only one square it doesn't change the fact that it is 100% logical. (When you finish the level with the last square, it doesn't matter where you place it right?)

[Anzu]

Hmm yes i think so.
I think anyway that it stays logical

I don't agree with the whole idea that only one solution is mandatory for logic problems, but it does make the puzzles seem tighter and better designed. It is annoying when you aren't given enough information beyond guessing whether a location is right or wrong, ala old Minesweeper. Fortunately, I didn't really encounter much of that in this game.

The following is from a "Logic Puzzle" blog:

"Logic puzzles should only have ONE solution, or else they cannot be solved using logic! It doesn't matter if they can all be accepted as a correct answer, the fact is that there is no longer a fully logical path to the solution, and that one is required to guess somewhere!"

I completely agree with this. There should NEVER be any guesswork in a true logic puzzle.
Unfortunately, "Tenrow "contains gaps in logic, multiple solutions and trial-and-error guessing.

Well, if there is a logical path to the penultimate configuration, and there is multiple final moves, there is no guesswork involved.

If you look at my post above regarding level # 8, you will see four different ways to place the tiles correctly. This is not acceptable for a logic puzzle. If there is more than one solution, the puzzle is broken.
Compare your game with Matthew Brown's "SquareCells" which only has one logical solution to each puzzle.

That happened because I tried to "fix" the puzzle. (The original puzzle had no such problem)

TRIED to fix it? It was already broke to begin with. As I stated before, no genuine logic puzzle has more than ONE solution. Whether or not you made it worse if of no consequence.

Tenrow's puzzle format is unique, and as I said before, a logical puzzle can have more than one puzzle if it is only the last move that has multiple possibilities. (Given that the penultimate step is unique and is logically deductible)
So, for a puzzle to be logical, the penultimate configuration is the one that needs to be unique.
And this was exactly the case with the original Level 8.
Of course, having a unique last move makes the puzzle better, but does not make it any less logical.
Matthew Brown went that extra mile, kudos to him for that. I didn't do that, so his puzzles are better than mine, but my puzzles are still logical.
