Sherlock is a computerized version of logic puzzles, where you're presented with a series of clues that help you to determine the exact locations of all the images on in the puzzle. 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 the images are located. Sherlock FREE contains 10 puzzles in each size for 30 puzzles total. The PRO version has 600 puzzles total, and the ULTRA version has 7500 puzzles total. The ZEN version has 150,000 puzzles total. The puzzles in the FREE, PRO, ULTRA, and ZEN versions are all unique, the four versions of the game share NO common puzzles.

Can you crack the code? Dyslock is a pure logic puzzle inspired by the classic Mastermind. A secret code is hidden. Each clue shows a guess and its pegs: how many symbols are in the right place, how many are in the code but in the wrong place, and how many are not in the code at all. Compare the clues, take notes, rule out the impossible, and find the only code that fits. No guessing, no luck: every puzzle is solved by deduction. WHAT PLAYERS SAY "solid puzzle game, fantastic note taking system" (TheRedrakerbz) "gradually builds from simple to challenging and on to impossible [but not really].
