Selecting a square changes it and the surrounding squares. Lights Out is an electronic game released by Tiger Electronics in 1995. [1] 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 adjacent lights.
Soma cube. The Soma cube is a solid dissection puzzle invented by Danish polymath Piet Hein in 1933 [1] during a lecture on quantum mechanics conducted by Werner Heisenberg. [2] Seven different pieces made out of unit cubes must be assembled into a 3×3×3 cube. The pieces can also be used to make a variety of other 3D shapes.
Puzzles have been built resembling Rubik's Cube, or based on its inner workings. For example, a cuboid is a puzzle based on Rubik's Cube, but with different functional dimensions, such as 2×2×4, 2×3×4, and 3×3×5. [118] Other Rubik's Cube modifications include "shape mods", cubes that have been extended or truncated to form a new shape.
Light Up (puzzle) Moderately difficult Light Up puzzle (solution) Light Up (Japanese: 美術館 bijutsukan, art gallery), also called Akari (明かり, light) is a binary-determination logic puzzle published by Nikoli. As of 2011, three books consisting entirely of Light Up puzzles have been published by Nikoli.
Megaminx. A 6-color Megaminx, solved. A 12-color Megaminx, solved. A 12-color Megaminx in a star-pattern arrangement. The Megaminx or Mégaminx (/ ˈmɛɡəmɪŋks /, / ˈmeɪ -/) is a dodecahedron -shaped puzzle similar to the Rubik's Cube. It has a total of 50 movable pieces to rearrange, compared to the 20 movable pieces of the Rubik's Cube.
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. The allusion to the deity is based on the notion that an omniscient ...
Meffert's. Country. Netherlands. The Gear Cube is a 3-D combination puzzle designed and created by Dutch puzzle maker Oskar van Deventer based on an idea by Bram Cohen. [1] It was initially produced by Shapeways in 2009 and known as " Caution Cube " due to the likelihood of getting one's fingers stuck between the gears while speedcubing. [2]
Optimal solutions for the Rubik's Cube are solutions that are the shortest in some sense. There are two common ways to measure the length of a solution. The first is to count the number of quarter turns. The second is to count the number of outer-layer twists, called "face turns". A move to turn an outer layer two quarter (90°) turns in the ...
