Description

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!

Comments on Einstein's Riddle for Android

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

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

★★★★★ 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.

★★★★★ 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.

★★★★★ 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

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

★★☆☆☆ many are impossible to solve (contradicting clues)

★★☆☆☆ 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.

★★☆☆☆ 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.
