Einstein's Riddle

Einstein's riddle or "Zebra puzzle" is a well known riddle attributed to Albert Einstein. In a neighborhood of five houses one is given some clues regarding the habits of the house owners and is asked to identify the one that owns the fish (or zebra in some variations).
It is said that only 2% of the population is able of finding the solution. I am not sure however, if this percentage refers to the people that are able to solve the puzzle without using a pen and a paper (or a computer). This is indeed very difficult and requires a beyond the average ability to hold too many pieces of information in one's mind at the same time.

This application provides an easier way to solve the puzzle. It presents the rules and the board in the same screen and allows you to easily make selections. It highlights red or green a rule automatically, when it is violated or fulfilled. It also offers easier variations of the puzzles, with fewer houses and properties.

I took off 2 stars because there's an ad after every game; I took off a 3rd star for the lack of new content. That being said, it has a cute, GUI interface. It may take awhile to get used to if you've only played text & grid logic problems. I found the 3x3 puzzles too easy for me, but used them to get used to the GUI style of play. However, I'm uninstalling as the ads are too numerous to enjoy playing. If they sold the game and offered additional, low-priced puzzle packs, I'd reconsider.

Need better instructions. Would help to see a demonstration or tutorial of the game, especially for players that have never heard of such a game. And when you've never heard of or played any game like it it's all foreign. Maybe I missed the area/button that is the tutorial. IF I did miss it then just let me know where it is and I'll reinstall to play.

It's good and addictive however the interface not friendly. Clues do not fit skin neither does the whole grind. Also it would help if there was the option to combine some clues together.

Nice clue and gameplay, but the UI is bad and frustrating at worst. You can't scroll and at earlier levels a box can't be clicked unless you tap it many time. Uninstalled.

My only gripe is a minor bug. The upperleft most square can only have a country input when the answer grid is enlarged. Other than that, this is a really fun logic game.

Great game if you like to think a lot and having quite some time to solve. I did all 6x6 (which are 100) and took me some months.

Not super easy to understand the clue system, but I'm catching on. Otherwise fun.

Crashed before even playing. I tried it on two different devices and it didn't work in either

Unfortunately the app stopped working with an update but nice to see a quick fix and this good game is back working

Does not work, if you try to start a puzzle it won't load it.

Gin. M. Jul 7, 2021     

There's no instructions so I have no clue how to play this game. I can't grasp the clue system. Have to uninstall

Lis. G. Jun 10, 2019

Loved this game so much. Very challenging.

D.. B. Apr 21, 2022

Need better instructions!

Clues contradict each other.

It would be nice if there's a note option where we could eliminate or mark the remaining values for each field.

Hours have been spent with this app

Solved every bit before submitting a review. It's good, addictive and has an interesting clue picture representation. I only feel the puzzles don't give enough hints and half the time they have to be solved not only by logic but by trial and error as well. There is also a small bug in the game: most often than not, the leftmost and rightmost colors cannot be set while in the 50% split screen. I had to enlarge the window, set the color and go back to normal size. Good game and good job overall ! P.S. Barbara Hanson is an idiot who left the dumbest review here.

This is the real Einstein game. Other apps lack one important logical piece, whether the object is to its right or left of another. This is important, otherwise, you can just simply guess. Controls/design could be a bit better, but gameplay is most important here

I love this game! It makes u think but easy that you can figure it out. Plus answers to check

Lin. B. May 20, 2018     

This could easily be a five star. There should be a 4x5 grid because the jump between 4x4 and 5x5 is too hard. Secondly, the 5x5 and 6x6 don't have enough clues so we have to guess most times and that is not logic.

Hel. L. May 6, 2017     

Good, but the arrows are hard to see and there are super annoying video ads

Tye. L. Feb 4, 2018     

Love the game the 6x6 really puts your brain to the test. Anybody figured out 6x6 #3

Bar. H. Sep 19, 2017     

The very first puzzle is incorrect. Uninstalled game immediately.

Mic. H. May 24, 2017     

Cute game. Fast play so great for standing in line. Passes the time with fun.

Fun and keeps me preoccupied when I'm killing time.

Best "Einstein game" that I seen before. Very useful for training imagination and logic.
