If you love logic puzzles, you’re sure to love nonogram logic puzzles: fill-in-the-blank puzzles that blend the deductive reasoning of Minesweeper with the pattern matching of Sudoku. Here are two highly-rated and free apps to try.
Griddlers Plus is the best Android application to solve popular logic puzzles also known as griddlers, hanjie, nonogram or picross. The goal of griddlers is to find out the positions of black or colored blocks using number hints in the white grid. The resulting solution of the puzzle is an image.
You can find more information about griddlers here: http://en.wikipedia.org/wiki/Nonogram. Griddlers Plus supports 4 types of griddlers puzzles: standart (black & white), colored, triangle and multi griddlers, and comes with lots of free puzzles.
– Supports standard (black&white), colored, triangle and multi griddlers.
– Advanced user interface controls for solving big and complex puzzles easily (zoom, scroll, multi cell selection, undo, redo, backup and restore solutions…).
Nonograms, also known as Hanjie, Griddlers, Picross, Japanese Crosswords, Japanese Puzzles, Pic-a-Pix, “Paint by numbers” and other names, are picture logic puzzles in which cells in a grid must be colored or left blank according to numbers at the side of the grid to reveal a hidden picture. The numbers are a form of discrete tomography that measures how many unbroken lines of filled-in squares there are in any given row or column. For example, a clue of “4 8 3” would mean there are sets of four, eight, and three filled squares, in that order, with at least one blank square between successive groups.
To solve a puzzle, one needs to determine which cells will be boxes and which will be empty. Determining which cells are to be left empty (called spaces) is as important as determining which to fill (called boxes). Later in the solving process, the spaces help determine where a clue (continuing block of boxes and a number in the legend) may spread. Solvers usually use a dot or a cross to mark cells they are certain are spaces.
It is also important never to guess. Only cells that can be determined by logic should be filled. If guessing, a single error can spread over the entire field and completely ruin the solution.
