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.
Einstein's Riddle is an ad supported game. Ads will be displayed during the game. However, if you manage to solve 20 4x4, 10 5x5 and 1 6x6 puzzles, then all ads will be disabled!

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.

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

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.

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