A sliding puzzle, sliding block puzzle, or sliding tile puzzle is a combination puzzle that challenges a player to slide (frequently flat) pieces along certain routes (usually on a board) to establish a certain end-configuration. The pieces to be moved may consist of simple shapes, or they may be imprinted with colours, patterns, sections of a ...
Like other sliding-block puzzles, several different-sized block pieces are placed inside a box, which is normally 4×5 in size. Among the blocks, there is a special one (usually the largest) which must be moved to a special area designated by the game board.
To solve the puzzle, the numbers must be rearranged into numerical order from left to right, top to bottom. The 15 puzzle (also called Gem Puzzle, Boss Puzzle, Game of Fifteen, Mystic Square and more) is a sliding puzzle. It has 15 square tiles numbered 1 to 15 in a frame that is 4 tile positions high and 4 tile positions wide, with one ...
A combination puzzle, also known as a sequential move puzzle, is a puzzle which consists of a set of pieces which can be manipulated into different combinations by a group of operations. Many such puzzles are mechanical puzzles of polyhedral shape , consisting of multiple layers of pieces along each axis which can rotate independently of each ...
Solving the puzzle requires a combination of logical techniques. [2] Numbers in each row and column restrict the number of possible values for each position, as do the inequalities. Once the table of possibilities has been determined, a crucial tactic to solve the puzzle involves "AB elimination", in which subsets are identified within a row ...
Lebbeus Edward A Hordern, known as Edward Hordern, (21 March 1941 [1] - 2 May 2000 [2]) was the world's leading authority on sliding block puzzles, and was renowned for his puzzle solving abilities. Hordern had an extensive mechanical puzzle collection and was an author on the topic of mechanical puzzles.
These puzzles do indeed have efficient solutions. It doesn't work for more general sliding-block puzzles. The fact that general sliding-block puzzles are PSPACE-complete to solve means that effectively, you can build computers out of sliding-block puzzles. Here is another paper, more accessible than the above references, which shows this: Hearn ...
The game consists of a 5 by 5 grid of lights. When the game starts, a random number or a stored pattern of these lights is switched on. Pressing any of the lights will toggle it and the four adjacent lights. The goal of the puzzle is to switch all the lights off, preferably in as few button presses as possible. [1] [4]
