Consistency puzzle game is a version of the well-known logic puzzle called zebra, often called Einstein's Riddle or Einstein's Puzzle because it is said to have been invented by Albert Einstein as a boy. It is also known as Sherlock puzzle because is a deduction puzzle game worth of the best detective.
In pen and paper version normally you have clues like:
1. There are five houses.

The Consistency puzzle game is similar but with graphical clues, where a grid is alredy set with
all possible items (persons, fruit, ...) per cell.
The goal of the puzzle game is to logically deduct all items positions in the provided grid, only one solution

Hello, I'd love an iOS version of this game. It's one of my time wasters back when I had an Android phone and kinda miss it now, one year later.
If you want me to contribute in porting or publishing it, I'm open for discussion.
Hi, I am so happy that you liked the game. The problem is that I am not maintaining the game anymore, and it uses "old technology" so it may be hard to even update the game for the current supported platforms.
Also, I don't have a MacOS or IOS so it would be very difficult for me to make a release on that platforms.
I think the game needs to be ported to a new "technology" , like flutter or something like that, but I don't see that happen on the near future.
The game is opensource https://github.com/fsvieira/consistency , if you want to try a port or something I will be glad to help.
Thanks
Judging by game's decription, you probably should remove "detective" tag. There is no detective game here, just a brainteaser
Hi, thank you for your suggestion, I put detective because its a deduction game, and detective came into to my mind. But I understand that it may be misleading, I corrected the tags and replaced detective with deduction and brain-teaser ;)
I hope you try it, it is challenging game.
Unfortunately, level 4 of 4x4 does not have enough clues to provide a correct solution.
Hi,
All puzzles should have only one solution provided by clues, I think all puzzles are correct, and until now I have not found a puzzle that can't be solved, all puzzles are computer generated and tested but there can always be a bug.
This being said, here is the solution:
1) Start removing items using left clues and middle clues, you should get something like this:
2) Apply left clues and same column clues, you should get this:
3) Now you got a difficult situation here, the easy way to solve this is using the "try mode" (the beaker icon), Start with the less number of items for example faces and start marking the correct items using clues, if you find a inconsistency then it means that you need to switch the faces. Start with the wrong face should be like this:
In this picture there is a inconsistency the scepter must be on the right side of coin, but there is already a paper in that position because of pear / face clue.
4) So the solution is to switch cases and solve the puzzle:
I hope this solves your problem and thank you very much for your input.
Using the try mode is optional and you can also infer new clues from existing ones, to try to solve the puzzle the hard way.
for example, the clues: coin > sceptre and sceptre > orange , will gives the clue coin > sceptre > orange.
Other clues like: pear | paper and girl | paper will gives the clues that the girl, pear and paper are at the same column.
Using this two clues we can figure out the girl position, the rest is easy.
