About 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.

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!

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

Y70%
by Y####:

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

V70%
by V####:

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

T70%
by T####:

Very challenging and logistic. Time passer

S70%

It is an awesome game

Y70%
by Y####:

Nice

J70%
by J####:

There is the ability to set waypoints, but not very useful. There is no way to eliminate choices that are impossible, and without that, it's just trial and error. You have to remember which rows apply to which category of icons, which is frustrating. Also, in some formats, there are icons in each category that won't be used. Not fun. Better ones out there. Uninstalling.

This game is awesome. It really makes you think and outside of your comfort zone. I love it after one day, I know the Christmas version and all future levels and puzzles, will not disappoint.

Bottom row of puzzles not responding to screen input. Nexus 5X Android 7.

Y70%
by Y####:

Most of the puzzles can only be solved by trial and error. It needs an undo button so you can go backwards and not have to restart the puzzle.

L70%
by L####:

Love the simplicity of the interface and the game itself. Though there should be an option to be able to eliminate choices from the list.

Y70%
by Y####:

Wonderful mind lubricant. Undo would make it easier, although trying to remember what you last did is certainly good brain exercise too.

P70%
by P####:

It so good. Harder than it looks at 5x5. Love the bookmark feature that allows you to go back without starting again.

U70%

However unplayable as the hitbox for the very first nationality seems to be 1 single pixel and it takes forever to hit it. This is the same in all the 3x3 through 6x6

Z70%
by Z####:

It's wonderful app I haven't seen it before. Look simple but more tricky. I love this app. Thanks for developing such a nice app in Android.

U70%
by U####:

Could do with elimination. (to eliminate the options rather than to pick the correct ones) this makes the harder puzzles a bit easier and reduce guessing. Otherwise very good app, thanks

I70%
by I####:

Fun, I'm only on the easy levels but I love this type of game and its well done.

F70%
by F####:

Many puzzles are unsolvable as the clues contradict each other. A shame, I loved the original puzzle and was glad to find this simple expansion on a theme.

U70%

Way too easy...finished it in less then 20mins

U70%
by U####:

On the 4x4 #11. It's unsolvable. I've reworked it many times and the correct answer shows as wrong. It's annoying.
