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 ...
The puzzle, unlit. The puzzle is based around a 3x3 grid of translucent panels, each panel being illuminated from below with red and blue LEDs. The bank of panels is mounted on a central spring-loaded pivot that can both slide a short distance in each of the four cardinal directions, as well as rotate or yaw slightly around the pivot.
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 ...
Henry Walton filed U.S. patent 516,035 in 1893 for a sliding puzzle of identically shaped rectangles. Frank E. Moss filed U.S. patent 668,386 in 1900 for a sliding puzzle of six squares and four rectangles, which is one of the first known occurrences of sliding puzzle with non-equal blocks. However, the early cognate of Klotski closest in ...
God's algorithm is a notion originating in discussions of ways to solve the Rubik's Cube puzzle, [1] but which can also be applied to other combinatorial puzzles and mathematical games. [2] It refers to any algorithm which produces a solution having the fewest possible moves (i.e., the solver should not require any more than this number).
Some of the puzzles are well known classics, some are variations of known puzzles making them more algorithmic, and some are new. [4] They include: Puzzles involving chessboards, including the eight queens puzzle, knight's tours, and the mutilated chessboard problem [1] [3] [4] Balance puzzles [3] River crossing puzzles [3] [4] The Tower of ...
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.
