Logic Detective

Logic problems require you to use and develop your analytical skills. Use the clues to fill in the logic grid. Each scenario requires you to deduce connections between items such as groups of people, places, times and objects. Fill in all squares on the grid to complete the puzzle.

What's that? You've solved all the puzzles already? Unlike other apps, this one randomly generates puzzles so the same scenario can be played over and over again with new sets of clues and answers giving each puzzle unlimited playability.

- Five difficulty levels for each scenario
- 72 scenarios to play over and over again with new clues and answers each time
- Multiple grid sizes
- Option to show mid-game updates of how many answers are incorrect
- "Be Lazy" button saves you having to manually put crosses in every square after you put a tick in that row
- Saves games between sessions
- Small, medium and large font sizes available via menu
- Layouts optimised for tablets and phones

Puzzles generated by this app are for non-commercial use only. This is an on-going project and updates will include new puzzles and better clues. Before you give this app a low star rating please contact us on twitter @goatsandtigers.

Can't get much better. This game has very good clues for the difficulty settings. However, the Very Hard clues still give a few straightforward phrases sometimes spanning multiple answers. Makes it a bit too easy for a very hard mode. I'd also LOVE the ability to print out the puzzles or save them to PDF or something. Fix these two problems and this app gets 5 Stars!

Okay, I guess I am different from most people who have played this. Due to low rating I almost passed up a fun logic grid puzzle that is actually entirely free unlike any of the other options on Play Store. The layout is a bit different, and threw me off at first, but once I got the hang of the ZOOM feature, I enjoyed it. It's OK if it doesn't auto "x" the squares (I think it does though) because I personally don't mind the challenge of check them myself like I would on paper. Not bad at all.

Numerous clues are incorrect. Makes some levels impossible to solve without constantly checking your answers and filling in the right ones from the hide/show answers option. I'd say at least a quarter of the puzzles have this issue, and I'm giving up after level 42. Also, not all the labels are shown along the grid, so you have to double tap into it to see which row/column is which option. Game isn't worth all the extra effort; it's not that great to play anyway.

Entirely too difficult to see all the clues without continually scrolling one by one. If you want to make a check mark on a square, you have to double tap. However, double tapping makes the box zoom in. When the box is zoomed in the auto fill option doesn't work. Overall, layout and display is terrible. Only got through 3 puzzles before I simply couldn't stand the design any longer.

I could look over the terrible design fairly easily, it had simple enough controls. Lots of grammatical errors and hard to read clues. My BIGGEST issue was that I got all the way to puzzle 41, and the app didn't show any clues at all. I hit the button for new clues and answers and it crashed the app every time I hit the button on that one puzzle, a button I had used in other puzzles with no problem. Uninstalling because of this.

Horrendous interface. They say double tap to zoom, and even put in a pop up message saying "looks like you're trying to pinch to zoom, double tap instead". Would've been better to just include a pinch zoom option instead. Add that making a correct mark doesn't automatically x out the rows surrounding it, and this just isn't worth it.

Don't bother! This app is worse than useless. The English is so bad that many of the clues are gibberish, a lot of the puzzles are missing vital information, and some of the clues contradict others, point to answers that literally do not exist in the puzzle, or are just plain wrong. It was incredibly frustrating, and so lousy that I have to think that the influx of positive reviews are either written by the developers or bought and paid for. A real disappointment for a logic puzzle fan.

autofill for lines added. Great game, but definitely needs an 'undo' function. if you make a mistake it's impossible to complete the game without using a hint.

Where are the clues? I see a description of each puzzle but no clues, just these people went to movies of different genres of different lenghts at different times. Thats a whole lot of possibi!ities

A. G. u. Oct 8, 2019     

Every thing is too condensed. The grid is small and difficult to see but when you zoom in its way too big.

A. G. u. Mar 19, 2020     

A major part of the grid was not present... making solving it impossible! It's a shame, because the number of "just logic grid puzzle apps" is dwindling down in Play Store.

A. G. u. Jun 21, 2019     

good enough game but would like a time indicator on it. and discovered some of the clue are wrongly given and unsolvable.

A. G. u. Sep 26, 2018     

Ads are shown throughout the game although this is not declared in the play store. The ads are dusturbing the screen.

Eun. K. Oct 17, 2020     

If it looks like a logic puzzle, acts like a logic puzzle and plays like a logic puzzle, you can bet that I'm going to love it!

T. F. Oct 8, 2021     

Couldn't even play the game because it won't show me any clues. Complete waste of time.

Most of the time is spent trying to put an X or a check in a box! I literally have a cramp in my right arm!

Jes. G. Jun 18, 2021     

Didn't say anything about containing ads, false advertising

great option but hard to use

It's sorta difficult to use

A. G. u. Jul 6, 2018     

The competition right now includes paid versions, or versions with ads that interrupt in the middle of moves with boring clues (30 clues worth of "x is either equal or non equal to y") despite the fact they don't ever change the answers. The programming of clue generation and wording took a fair amount of thought to pull off as nicely as they did. Really nice controls with a be lazy mode and autofill added since last reviews.

You've improved but you need to still work on it. I tried to put down points but it didn't allow more than 500 letters. I would suggest you check out the functionality of logic grid on Brainzilla website also their zebra puzzle. You've good puzzles but functionality is cumbersome, and crosses are uncomfortable to the eyes apart from other issues. I'm uninstalling it now.

A. G. u. Jul 15, 2018     

This is a great game, it is free, and they have bad reviews only because of the older versions. It is the only endless logic puzzle game that is free.

A. G. u. Jul 30, 2018     

Started multiple new games, did not generate questions. The three dots were not there, no instructions.

A. G. u. Jun 22, 2018     

Not bad, but very tedious. Would be much better if X's automatically filled the rest of the lines that the check marks were put into.

A. G. u. Jun 15, 2018     

I love this game! I absolutely love that you can reset the clues.. That way you don't finish and uninstall. They revamped the clues, especially the very easy. It takes a bit of logic to get to the end, as said, the higher level, the more logic. But hey, that is what the game is about!

A. G. u. Jun 14, 2018     

Don't bother.

A. G. u. Jun 13, 2018     

Try again

A. G. u. Mar 18, 2018     

Seems to have a variety of logic scenarios. Only the one issue, but it does make the game so frustrating that it became unplayable. My fingers are too big (they're not that big) for the squares, meaning sometimes I accidentally click a square adjacent to the one I want to. It means I spend to much time rectifing errors than figuring out the problem. Easy solve, allow the ability to zoom in on the grid. Larger grid means less errors. Sort this out, I'll not only be back, and with 5 stars
