The cube stacking game is a two-player game version of this puzzle. Given an ordered list of cubes, the players take turns adding the next cube to the top of a growing stack of cubes. The loser is the first player to add a cube that causes one of the four sides of the stack to have a color repeated more than once.
Each valid solution to the puzzle arranges the blocks in an approximate 3 × 3 × 3 grid of blocks, with the sides of the blocks all parallel to the sides of the outer cube, and with one block of each width along each axis-parallel line of three blocks. Counting reflections and rotations as being the same solution as each other, the puzzle has ...
The test was developed in 1920 by psychologist Samuel C. Kohs (1890–1984), a student of Lewis Terman, [3] building on earlier and similar designs (such as Francis N. Maxfield's Color Cube Test). [4] Kohs described the 1920s version of the test as a series of 17 cards which increase in complexity as the test progressed. [5]
A block design test is a subtest on many IQ test batteries used as part of assessment of human intelligence. It is thought to tap spatial visualization ability and motor skill . The test-taker uses hand movements to rearrange blocks that have various color patterns on different sides to match a pattern.
The objective is to assemble these pieces into a 4 x 4 x 4 cube. There are 19,186 distinct ways of doing so, up to rotations and reflections. The Bedlam cube is one unit per side larger than the 3 x 3 x 3 Soma cube , and is much more difficult to solve.
Rubik's Bricks, [7] a puzzle produced under the Rubik's branding, is a similar puzzle made of 27 cubes, but the pieces are formed by joining cubes either by faces or by edges. There are exactly 9 such ways to join three cubes, so the puzzle can make a 3x3x3 cube. The individual cubes are colored in such a way as to give a unique solution.
A particular solution; this illustrates the B 20,0,0 constraint which forces a single color along the perimeter, while also maximizing the largest contiguous single-color area within the perimeter MacMahon Squares are an edge-matching puzzle first published by Percy MacMahon in 1921, [ 1 ] using 24 unique squares with 3-color patterns; each of ...
The Mirror Blocks, also known as the Mirror Cube and Bump Cube, is a type of combination puzzle and shape modification of the standard 3×3×3 Rubik's Cube and was invented in 2006. The puzzle's internal mechanism is nearly identical to that of the Rubik's Cube, although it differs from normal 3×3 cubes in that all pieces are the same color ...
