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. 50,000 puzzles in each size for a total of 150,000 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.

4 difficulty levels, 5 different sizes. Thousands of unique grids to play. LogiBrain Binary is a challenging logic puzzle game. Although the binary puzzle consists only of zeros and ones, solving is certainly not easy. LogiBrain Binary includes 2000+ puzzles in different sizes and different levels of difficulty; easy (1 star), medium (2 stars), hard (3 stars), very hard (4 stars); It seems simple, but it is yet addictive! We can guarantee you hours of fun and logic. What are binary puzzles? A binary puzzle is a logic puzzle in which numbers should be placed in boxes. Most grids consist of 10x10 boxes, but there are also 6x6, 8x8, 12x12 and 14x14 grids. The aim is to fill a grid with ones and zeros. In a given puzzle are already some boxes filled. You must fill in the remaining boxes which must respect the following rules: RULES 1. Each box should contain a "1" or a "0". 2. No more than two similar numbers next to each other in a row. 3. Each row should contain an equal number of zeros and ones (14x14 grids at each row/column 7 ones and 7 zeros). 4. Each row and each column is unique (No two rows and columns are the same). Every binary puzzle has only one correct solution, this solution can always be found without gambling! The first click on the empty field sets the field to "0", a second click to "1", a third click empties the field. Simple rules but hours of puzzle fun. GAME FEATURES - 4 difficulty levels - 5 grid sizes (6x6, 8x8, 10x10, 12x12, 14x14) - 2000+ puzzles (no hidden in-app purchases, all puzzles are free) - Search for errors and highlight them - Automatic saving - Supports tablets - Check for errors and remove them - Get a hint or the complete solution when you want - Go steps back and forth - A great workout for your mind TIPS Find duos (2 same numbers) Because no more than two of the same digits may be next to or placed under each other, duos can be complemented by the other digit. Avoid trios (3 same numbers) If two cells contain the same figure with an empty cell in between, this empty cell can be filled in with the other digit. Fill rows and columns Each row and each column has the same number of zeroes and ones. If the maximum number of zeroes has been reached in a row or column it can be filled in a one in the other cells, and vice versa. Eliminate other impossible combinations Make sure that certain combinations may or may not be possible in rows or columns. If you like LogiBrain Binary, please take the time to give us a nice review.
