Chord
Concept
Sudoku-like puzzle game. Fill in the correct numbers to solve the puzzle.
How To
The puzzle consists of numbers along the outside of a circle. The circle is separated by the top half and the bottom half, and numbers from the top half are connected to numbers on the bottom half via a line. Depending on the size of the puzzle ('X'), there will be 'X' numbers on the top half, and 'X' numbers on the bottom half of the circle. Some of the numbers will not be filled in. The goal is to fill in the missing numbers based on the rest of the puzzle to correctly solve it.
Rules
- No duplicate numbers on the top half. No duplicate numbers on the bottom half.
- If two numbers are connected by a line, they cannot be the same value.
- Each number on one half of the circle must be equal to one of the numbers on the opposite half of the circle which it's line intersects.

Hi,
Does this logic already exist in a game or did you create everything?
I love Sudoku so I think this idea is great!
But for me there should be additionals rules.
When I played a size 4 it was really easy, but in size 6 it started to be unresolvable.
With the current rules I have found cases where several solutions are possible. This is not the case in a Sudoku where only one solution exists.
Here, if I'm not mistaken, the 5 and 4 on left are good, but after that there are not indices for find the next numbers.
All these solutions follow the rules but are not good?
Why?
Here is the correct solution (below) and I don't know why.
Maybe a new rule could render only one solution good.
For example, the numbers on the same "column" cannot be the same. In this case in the first picture, the B would be wrong because the numbers 2 and 6 are on the same column. the same for the D with the number 2.
Unfortunately this slight problem makes the experience less replayable and more frustrating.
Hi CDJimmy, thanks for your interest in Chord! To answer your first question, as far as I know this logic does not exist in any other game. I created everything (the logic, rules, algorithms, puzzles, etc...) in this game myself.
If I'm understanding you correctly, your concern is that some puzzles have multiple solutions, or no solutions. The way the game is intended to work is that each puzzle should only have 1 possible solution. I took a look at the images you provided, and it looks like they do not follow all of the rules. Each puzzle in the pictures you provided break the same rule:
"Each number on one half of the circle must be the same as a number on the opposite half of the circle that it's line intersects."
Basically, a line coming from a number on top must intersect a line coming from the same number on the bottom. I added to your screen shots to show where this rule is being broken.
Picture A:
The line coming from the 2 on top, does not intersect the line coming from the 2 on bottom. Same with the 6s.
Picture B:
The line coming from the 3 on top, does not intersect the line coming from the 3 on bottom.
Picture C:
The line coming from the 2 on top, does not intersect the line coming from the 2 on bottom. Same for the 1s, 3s, and 6s.
Picture D:
The line coming from the 3 on top, does not intersect the line coming from the 3 on bottom. Same with the 1s and 6s.
As for the solution picture, the reason it is a correct solution is because it follows all of the rules.
1 through 6 on the top.
1 through 6 on the bottom.
No lines have the same number on either end point.
Ever number on one half of the circle intersects the same number on the other half of the circle.
Hopefully that makes sense, and answers your questions. Please let me know if I missed something. I appreciate the feedback, I'm always looking for ways to improve.
Thanks again for playing the game! Let me know if you have any other questions.
Oooh ok ^^ than you I understand ! it's better like this lol. I'm not english so maybe it's just my own mistake.
The reason why I failed in this rule is in the tutorial. In explanations 6/10 and 8/10 you saied :
"the line only intersect...".
In first I understood this rule apply only if 2 lines intersect but not it they are more than 2.
That's why in my example I fill out numbers 5 and 4 because this line only intersect with 5 and 4.
I understand now ; if only 2 line intersect you know wich number to put inside. BUT if there are more intersection the rule stay the same ^^
So I can't judge with my non-English reading. But peraps the "only" explanation could be made more excplicit.
Hope it's help ;-) I know feedback is important and most people never notify when they find problems.
this is brilliant I love this idea it needs way more polish but it's great anyway
Hi Ekim, thanks playing Chord!
I agree, the game definitely needs a polish. Unfortunately design isn't my strong suite (I lean more towards the technical side). Wasn't sure if anyone would really even be interested in this type of game, so decided to release as is.
I appreciate the feedback, maybe I'll look into having a designer help polish the game, and make it look a bit more presentable.
If you think about design, I propose to highlight line when your mouse pass on numbers. It can help when you have more than 8 lines.
