Sherlock is a computerized version of logic puzzles, where you're presented with a series of clues that help you determine the exact locations of all the images on the playing board. The puzzles are all 4x4, 5x5 or 6x6. Each row of the puzzle contains images of the same type (faces, houses, numbers, fruit, street signs, letters, etc). The game scrambles the locations of the items in each row (without showing you their locations) and then presents to you a set of graphical clues that describe the positional relationships of different images. You use the clues to deduce where things can't be (and where they HAVE to be) until you know where all of the images are located. 2500 puzzles in each size for a total of 7500 puzzles! The puzzles in the Free, Pro, Ultra, and Zen versions of the game are all unique, the four versions of the game share NO common puzzles.

Go-to brain-teaser


Love these games and the logic behind them. They never get too hard, and there's always a hint available -- just a hint! -- if you just don't see that one key move. Everett's games always work perfectly on my iPads, and I enjoy the challenge of keeping my times down. I have to admit these games are a huge challenge for big fingers on an iPhone, but that's not where I play it, so it's a great brain-teaser for those moments whenI need to clear my head.

Probably my favorite logic game. Never gets old. I started playing this game when it was a DOS game — that’s before Microsoft Windows for you young people. Works ok on iPhone for 4x4 and 5x5 games. The 6x6 games are a bit challenging for my eyes and fingers. I used my iPad for the bigger grid.

The best Einstein’s Puzzle app

This is far and away the best app for the Einstein’s Logic Puzzle. There are different sizes available and more than enough games to keep you busy for a long time.
